Some thoughts about peep sights

by Tom Gaylord, a.k.a. B.B. Pelletier

This is a subject that is dear to a lot of experienced shooters and a turnoff to younger shooters. Peep sights are a blessing to those who have discovered how easy they are to use, but they are avoided by shooters who aren’t familiar with them. The common misconception is that a peep sight is somehow more complex than a traditional open notch rear sight, but the truth is that the peep sight is actually simpler and faster to use than the open notch.

With an open notch sight, you have to align the rear notch with the front post. There can be several different variations of how it works, such as post and bead or squared-off front post, but the process of using them is the same for all of them. The rear element and front element must be aligned, then held against the target in a certain location (i.e., 6 o’clock hold or center hold).

With a peep sight, you don’t do that. You just look through the rear hole and align the front sight element only against the target. Your eye uses the peephole to adjust your vision by forcing your pupil to adjust for the best depth of vision. It’s an unconscious and automatic response to looking through the small peephole; and, if you allow your eye to do its job instead of fighting it, your brain will help you obtain a more precise sight picture than with open sights.

There are shooters with remarkable vision who can sight with open notch sights extremely well. But if you don’t have great vision, and by that I mean if your vision is average or worse, the peep sight should work better for you. But that’s only for those who don’t fight the rear sight and just look through it.

Peephole sizes
Today, I want to address something that I’ve seen discussed a lot on the internet, and that’s the size of the peephole. I see that many people feel the hole must be large or they cannot use it. Indeed, I’ve seen several peeps that have been drilled out by their owners. The fact is that there are good reasons for both large and small peep holes.

Large peepholes
Large holes allow more light to pass through; and, when used, they acquire the target faster. They’re used on American military arms like the M16, the Krag, the 03-A3 Springfield, the M1 Carbine, the Garand and many others. They’re also found on slug guns used for deer in brushy forest hunting situations where speed is more important than precision.

Garand
The M1 Garand peep is about average size for a battle sight.

03-A3
The 03-A3 sight adjusted for windage as well as elevation. Not all of them did. I can shoot MOA with this sight.

Carbine
The M1 Carbine peep was a rough and ready sight. The rifle wasn’t that accurate, so the sight didn’t need to be precision.

No. 4
The battle sight in this No. 4 Enfield is huge. When the sight standard flips up there is a hole less than half this size. It adjusts only for elevation.

Can such large holes be precise? Yes, they can. I have shown you at least one one-inch five-shot group shot with my 03-A3 Springfield at 100 yards. But the norm would be a larger group. Even the Garand would shoot about a two-inch group at 100 yards on most days. Your goal with a large peep is minute-of-bad-guy.

One secret I’ve learned about using a large peep hole with greater precision is to hold the sight away from my eye. The farther back I place my sighting eye, the more precision I get from a large hole. I didn’t invent that idea; I learned it while shooting the Buffington peep sight on my Trapdoor Springfield that was made in 1875 (the rifle, only — the sight didn’t come about until 1884). The Buffington sight puts the rear peep hole about 14 inches from the sighting eye, and the hole is not that large. You would look at it and imagine that you could never use such a sight, but the truth is that when there’s enough daylight that peep gives precision that rivals the finest tang target sights found on target single-shot rifles. The reason is because of how far the hole is from your eye.

Buffington
Col. Buffington designed this rear sight that combines a peep (several, actually) and a notch. It can be used for long-range precision fire. A great many buffalo fell to this sight on this rifle.

Small peepholes
A small peephole passes less light and forces you to hold your sighting eye closer to the hole to see the sight picture. Many sights with small holes also have some kind of flexible shade to shield the sighting eye from light that’s not coming through the peep hole, thus sharpening the sight picture noticeably.

FWB 300S
The precision FWB peep sight has a large rubber light shade to keep the sighting eye in the dark.

Crosman 160
Crosman mounted their version of a Mossberg S331 peep sight on the 160 target rifle. This sight, alone, is worth at least $75 today. Notice how small the hole is. That’s what’s needed for precision.

Small peepholes take longer to use but provide a more precise sight picture. Use them when fractions of an inch are important, such as when target shooting or when hunting game at longer ranges such as 400 to 600 yards.

Ballard
This is Ballard’s mid-range peep sight mounted on the tang of my Ballard rifle. My eye is so close to the hole that I push the sight forward when the rifle recoils.

The secret to using a small peephole is to get as close to the hole as you can. Do this even with recoiling rifles. My Ballard, for example, is in caliber .38-55 and kicks about like a 30-30, yet I put my eye less than an inch from the peephole. I have to because it’s so small that I couldn’t use it if I was much farther back. When the rifle fires, my forehead always folds the sight forward as the recoil brings the gun back. That’s how I know I’m using the sight to its best ability. Of course, if the sight doesn’t move when you hit it, you don’t want to do this!

When my FWB 300S target air rifle comes back in recoil (the action moves in the stock to cancel the feeling of recoil) the rubber eyepiece always pushes against my eye. That’s how I know I’m sighting correctly . It works okay on that rifle, but my HW55CM comes back a little too aggressively, and I’m more cautious about holding that sight close to my eye.

Use BOTH eyes!
It is of paramount importance to keep BOTH eyes open when using a peep sight. If you close the non-sighting eye, the peephole will also close up. It’ll do so variably, depending on how much you’re squinting to close the other eye, and the result is you no longer have a round hole to look through. I told you about the man who was shooting the M1 Garand a couple weeks ago and was closing his off eye. He was getting 12-inch groups at 100 yards from a rifle that was probably capable of groups one-sixth that size.

If you want to see how this works, take a piece of card stock and poke a hole in it. Look through the hole with both eyes open (one eye looking through the hole and the other eye just open). Then, as you’re looking through the hole, close your non-sighting eye and watch what happens. The hole seems to close up! That’s what you are doing when you close your non-sighting eye while using a peep sight.

Peep sights are an advancement over open sights. They don’t work for everyone, because those with severe eye problems often have trouble using them. But the majority of people can use a peep sight and obtain better accuracy with less time spent if they don’t fight the sight. They’ve been used on all American military battle rifles since 1884; and though the move is now toward optical sights, a peep will probably remain as the backup sight for some time.

If you’ve never tried a peep sight, you owe it to yourself to give it a try. Use this report as a primer for learning how to use the sight and see if it doesn’t give you greater accuracy with less work.

    I absolutely love a peep sight. If more people tried them out, the optics industry would likely see a drop in sales. The reason manufacturers do not put them on more airguns and firearms is cost. It is hard to get cheaper than a couple of small pieces of stamped metal. Marketeers have convinced most of us that powerful optics or illuminated dot sights or a combination of both is what is needed, but as has been mentioned here and previously, a decent peep can give wonderful results at long range and usually not as subject to damage and is usually less expensive than good optics.

  • Michael Says:

    This has really picked up my interest. If a large holed peep may need up to 14″ between it and the eye, would it not be perfect for a handgun? It sounds like it might well work with the Marauder air pistol. Has anyone tried it? Which one would be good for that use?
    Another question: in aligning the peep, is it the case that you don’t have to align with a front post? How does that work?

    • caveman Says:

      Michael,
      I know a few pistol silhouette shooters that use “peep” front and rear sights with great success.
      You may be confusing a front post with a front aperture which you simply put the target in the center of the opening.

    • B.B. Pelletier Says:

      Michael,

      Yes, peep sights have been used on handguns in the past. I guess they suffer from the same problems as on rifles, only on handguns the resistance is even greater. I have never tried tham on a handgun, so I have no experience to tell me how well they work.

    • Wulfraed Says:

      I have difficulty visualizing the use of any “rear” peep that is more than a few inches from the eye.

      With a peep that is close to the eye (especially target types), my experience has been that if you can see through the peep, your eye is aligned. This gives, effectively, only three points of alignment: target, front sight, rear sight — one’s eye is taken out of the equation (to see through the close placed peep, the eye is already centered) — or two line segments: targetfront, frontrear, and since frontrear are fixed with the bore, the front sight to target is the only alignment factor that needs to concern one.

      Moving a peep further away produces four points of alignment, targetfrontreareye, or three line segments that need to be aligned — one has to wiggle one’s eye around to bring the front sight into view through the opening of the peep.. That doesn’t seem much different from the hassle of common post&notch sighting — except rather than having to align with various shaped notches with indeterminate “top lines” one has a circle to center within.

      • Wulfraed Says:

        My pardon… I forgot the software strips <> unless using the HTML identities &lt;&gt;…

        Read those concatenated terms (ex) “frontrear” as “front<>rear”

    • johnny b Says:

      Actually, the Hipoint pistols all have peep sights. I’ve never used one but I’ve heard that they actually work very well.

  • dangerdongle Says:

    Good article! I happen to love peeps, but I always take a ribbing over them at the range..usually, as you mentioned, by the younger guys. But my eyesight isn’t what it once was and they work great for me.
    Too bad we can’t get the manufacturers to get over their fiber fascination and go with peeps instead!

    • twotalon Says:

      Everybody knows that scopes are superior to “irons”. Scopes fog up when you breathe on them, fog from temperature change, go out of zero from temperature change, light up when the sun hits the front lens, go out of zero from bumps, break from recoil, have parallax issues, can be impossible to use at very close range, and can cause you to go nuts because you don’t know if a problem is caused by the scope, rifle, or both.
      Seems like good enough reason to make fun of you for using peeps.

      • G.Austin Says:

        Great write up on scopes. Hollywood has gone too far in misrepresenting scopes.

      • dangerdongle Says:

        Well, these are the same guys that think my Swiss 96/11 is a black powder weapon and can’t understand why I’d want to shoot something that has to be loaded one-at-a-time, so I don’t take ‘em too seriously.
        It’s a shame though, a whole generation of shooters thinking a red dot on an AR is the only way to go.

    What’s up with the new H&N pellet for $5.25/500???

    H&N Excite Econ Pellets, .177 Cal, 7.48 Grains, Wadcutter, 500ct

    An H&N pellet at this price range is unheard of. BB you’ve “got” to incorporate this ammo in one of your future accuracy tests.

      I was just recently made aware of these new lower-priced pellets from H&N. I will order some for a test.

    It is easier to produce exact notes from a piano, but a violin can produce a wider range of notes as well as infinite variations and gradations. It is easier to learn to ride a bike with training wheels, but no one rides bikes with training wheels in the Tour de France. Wheelchairs are an advancement in mobility to those who cannot walk. These are some of the ways I would view peep sights metaphorically when compared to open sights. When peeps are compared to open sights for shooters who are visually impaired in such a way that they cannot see open sights, peeps might be deemed appropriate. When one must teach shooting to a large number of people with no prior experience or any particular aptitude, peeps may be more effective. When one wants to shoot round targets at specific, known distances — or large targets within a certain range, peeps may be more precise or effective. When one wants to learn the fundamentals of shooting and attempt to master all aspects of the discipline, peeps are a poor second to open sights and a cheat. “Greater accuracy with less work” is all that needs to be said, but in my view it is only half the story.

    I do “like” them better than scopes :)!

    • caveman Says:

      BG Farmer,
      “cheat” really?
      It aways amazes me when someone is willing to spend top dollar for a scope but don’t see the value of a good set of aperture sights. I think good sights are just as importing as the barrel, action, or trigger.
      BTW, You don’t see people riding a big fat wheel single speed Schwinn in the Tour da France ether!

      • BG_Farmer Says:

        Caveman,
        A bit of my tongue was in my cheek with that post, but I really don’t see the need for anything more than fixed open sights in shooting competitions, except that people feel better about themselves (because they shoot better with less effort) with peeps. The shooters with the most discipline and practice, best physical conditioning, most fortunate biological disposition (including vision), and luck in combination with their experience should win every match (though it won’t always be the same shooter) regardless of the equipment allowed. Peeps are standard (when allowed by rules) because they are an advantage that everyone wants and do equalize vision capabilities between shooters. I think it cheapens the competition in that regard, though it does raise the scores. How’s that for an alternative viewpoint :)?

        • caveman Says:

          BG Farmer,
          I figured and am glad you have thick enough skin not to get bent out of shape, my reply was “A bit of my tongue was in my cheek ” as well. I’m a big fan of irons my self and have used them my whole life. Peeps are no longer an advantage to me because of scare damage on my cornea from eye surgery (5 of them). I still use irons but at some time in the near future I’m going to have to learn how to deal with a scope and all the problem that twotalon mentioned above. I’m not looking forward to it.

          • twotalon Says:

            Don’t sweat it too much. I have bad eyes too that don’t work very well under various circumstances.
            You can get lucky and have everything work for a long time, but with some limitations. You have limitations with any kind of sights.
            Different kinds of sights all have +- to them for when they will be the best option or not.
            There are a lot of gremlins to watch out for with scopes including mount problems . The more you know, the easier it is to know what to do or where to look for problems.

            twotalon

          • BG_Farmer Says:

            We’re good as far as I’m concerned. Sorry to hear about the eye problems — scope is better than not shooting, for sure, though you’ll start to wonder at times, esp. if you put it on a springer! And don’t give up on the irons without a fight. A member of my ML’ing club was 82 when he died of bladder cancer this summer, but only a couple of months before, he had split the playing card on his last woodswalk (quite poetically, and the last station as well — normally we try “within reason” to find the pieces, but that time several of us spent a long time to find them, knowing that he most likely would not get another chance). And he had done quite well in line matches also, though he often got so tired halfway through that he couldn’t finish. Anyway, a competitive spirit and experience can overcome a lot, and the story above is one big inspiration for me (fat, myopic and forty-something, but really not bad considering how little effort I took early on), so I’m hoping it will inspire you in your more serious physical trials also! You never know what you can do if you give up trying…

    • Matt61 Says:

      Ha, ironclad traditionalist for sure. :-) Well, do open sights have any advantage over peep sights other than requiring more work? This leads you down the slippery slope of dispensing with sights altogether and going for the zen archery.

      I will say that I was quite taken with Elmer Keith’s description of using holdover with his pistol sights with great precision. He even invented his own model with graduated sights. There is quite an art to this that is not really possible with peep sights. But otherwise, I don’t know what else you get with the open sights.

      Matt61

      • Wulfraed Says:

        Since most open sights are mounted on the barrel, one doesn’t have to contend with misaligned barrel-receiver joins (if you look down on top of my Marlin-Glenfield 60c, there is a distinctive leftward angle, the stock inletting even matches — thin on the left end). On a break-barrel airgun, this means the sight alignment doesn’t shift with changes in the barrel lock-up.

      • BG_Farmer Says:

        My favorite part is that windage and elevation can easily be changed on the fly with the open sights without losing zero or touching anything, just as you describe Keith doing. I don’t like mechanical adjustment of sights while shooting (or ever really; sight in once, and that should be it, esp. if the sights are peened in or soldered on). Spend enough time with a rifle and it is amazing how easy it can be to use “Kentucky windage” and/or a “coarse or fine bead” (for elevation).

        Wulfraed also makes a good point.

  • se mn airgunner Says:

    BB,

    In your article you say for small peep holes get as close as you can. My only experience with a peep sight is on my Crosman 1377 pump air pistol. Obviously you don’t shoot a pistol pulled up against your face. What is the purpose of the peep sight on such a gun? I turn the sight upside down for the traditional open sights.

    Could it be there for when you buy the custom stock and make it into a carbine? That’s my only guess.

    Thanks!

    • B.B. Pelletier Says:

      se nn,

      According to Crosman’s head engineers, that was the only reason for the peep on that pistol — for the optional shoulder stock. It’s cheap to put both a peep and an open notch on the rear sight, so why not?

      B.B.

      • Gene Says:

        I have a laser on my 1377 carbine. But I use the stock peep on my 2240 carbine. This is my first peep and it did take some time but now I love it. It is so fast to sight in.

  • duskwight Says:

    Back in Russia, back in action.

    This week is going to be marked with epoxy and heavy clamp oppression. With some cutting and threading, as my receiver arrives. I hope I will be able to completely assemble my rifle’s action by the end of this week and start working on its stock.

  • Mac Says:

    I don’t usually comment here, but I really liked this Blog. One of the best uses I have found for the peep is in training new shooters. With open sights, using the same gun with multiple shooters is a pain because POI changes with each shooter. With a peep rear and a globe front, POI seems to remain relatively constant from shooter to shooter, making the training go much faster.

    • B.B. Pelletier Says:

      Mac,

      Hey! Welcome to the blog!

      I think the ease of use is the principal reason the U.S. has kept peeps on their battle rifle for the past 125+ years. It’s too easy to train a new shooter to be a good shooter.

      B.B.

      • Matt61 Says:

        I understand that the latest iteration of the AK for the Russian army is fitted with peep sights to replace their old open sights with the miniature sight radius. So, the Russians are finally coming to the party.

      Mac,

      Great observation.

      Wish I was smart enough to have thought of that. I’ve been graduating young kids at my club from shooting a walther 53 (little bit of recoil) with open sights to shooting a browning take down with long rifles (slightly more recoil) with open sights. Even benched I’ve noticed the shooters group in different places. Assumed with these young kids it was cant since I see them mounting the gun differently to get the right sight picture.

      I don’t want to alienate them from the FUN of the experience so I haven’t been much of a task master with cheek placement and after the first few shots on paper they quickly want to shoot at the hanging balls or potatoes painted red. They get bored with paper quickly.

      A peep sight for these young shooters makes perfect sense and should minimize the variations in grouping shots between shooters.

      Do you have a suggestion for the type of insert for the front globe sight that new shooters find easiest to use?

      kevin

      • Mac Says:

        As long as the front aperture is big enough to see the entire potato, or what ever they shoot, it really doesn’t matter. Just have them put the potato in the middle. The closer the match of target to front aperture size, the better the accuracy potential. I like to see a thin rim around round targets. I find the aperture sights build shooter confidence so when they go to open sights, they already know they are capable, if they can master the technique.

    • David Enoch Says:

      Hi Mac,
      You should speak up more often. Even BB listens to you! See you in Little Rock next year.

      I started my girls shooting with an IZH 60, well actually I had two at the time. I tried open sights, the aperture sight plate that they provided to change the open sight to an aperture, and a small scope. Both girls had trouble with open sights and the scope but both of my girls instinctively picked up the aperture and were instantly hitting cans.

      My objection to aperture sights is that I like to shoot at small bullseyes (20 or 30 on a 8 1/2″ x 11″ sheet) and small spinners. I cannot see small targets with an aperture sight from 30 yards away or so. I can do OK if I shoot at a 4″ or 6″ target though.

      BB, I enjoyed the article. Keep up the good work.

      • Mac Says:

        David, I use a 1.5 diopter on my aperture sight. It magnifies the front sight disc. I use a front disc that is clear and the hole just floats there. With the magnification, I am able to use an extremely small front aperture size, 1.8mm or smaller. With that setup, I can hit empty 9mm cases at 25 yds, on a good day. There is a past blog that touches on it, maybe something about mini-sniping. Mac

  • Desertdweller Says:

    In our local 4H bb gun program (and the air rifle school that follows it) all shooting is done with peep sights. The bb gun school introduces youngsters, often with no prior shooting experience, to shooting.

    The kids seem to take to using these sights naturally.

    My Marlin 39a will always wear a receiver peep sight. I, personally, am not a fan of open rifle sights, because my first rifle iron sight experience was with my marlin. Open sights are much too niggly for me.

      Agghh, so jealous. That Marlin 39A is a great rifle. But you don’t suppose that Annie Oakley used a peep with it do you?

  • chuckj Says:

    Another excellent blog article. I, too, like peep sights. I have them on my Challenger and prefer them over a scope. However, with help from this blog and from Victor in particular, I am beginning to use the open sight notch and flat blade as second nature on my IZH-46M.

    I find shooting a pistol very challenging. I’m also finding that most of my pistol problems are resolving themselves through use as my brain’s hand/eye coordination improves. I experience this during a normal shooting session. I thought I would start out at my most steady aim and get more shaky with each shot. But I see my aim becoming more steady as I progress through the session. Of course, eventually, I do tire out. My steadiness is like a bell curve. Also, as my strength increases, so does the top of the curve. But I don’t think the strength increase is having as much of an effect now as the hand/eye coordination is.

    -Chuckj

    • Matt61 Says:

      I’ve convinced myself that pistol shooting is much more challenging than rifle shooting for the simple reason that it is hanging way out from your body unsupported. And for this same reason, the one-handed hold is far shakier. QED >:-)

    • G.Austin Says:

      You can buy an adapter to fit a merit peep sight to you 46M along with a hooded front post to avoid false aim points. I have one for my 46M and love it. It’s like having a rifle in a pistol form. But it won’t be a good notch and post training tool after the conversion.

      • chuckj Says:

        G.Austin,
        Thanks for the 46M peep info. I’m going to stay with the open sights for now, but it’s good to know there is an alternative if needed.

  • Mike Says:

    Peep sights are great. My Marlin 39a also has a vintage Redfield Receiver Sight on it. I also use them on my Sheridan “C”, Ruger 10/22, and a number of military rifles. They are fast and accurate, what’s not to like!

    Mike

    • Matt61 Says:

      Mike, I can’t believe it! I’m coming around to your way of thinking on AR-15s. I’m thinking specifically of the LWRC products. They have a piston design that goes back to the AR18 designed by Stoner himself. So, there’s continuity. And the record of this particular design in the German G36 and some other rifles is unblemished. This design is fairly clever involving certain self-cleaning and self-scraping functions. And it has been mated with this new material called Cerakote or Melonite that is like a lubricant so that the gun hardly needs to be cleaned, just wiped down, so you’ve got the reliability. It seems to be plenty accurate. It is chambered for both 6.8 and 7.62 calibers. And the design gives you access to all the ergonomic and optical accessories of the AR platform. By Jove, they might have finally done it!

  • Matt61 Says:

    Fascinating blog. I’ve wondered about a comment by Col. Jeff Cooper on peep sights. He claims that a large ghost ring is not only faster but more accurate than a smaller target aperture. With the smaller one, you are consciously making adjustments, but with the large ring, you don’t even see it. You concentrate on the front sight, and your eye automatically centers the rear sight. Sounds like the Jaws of the Subconscious. Anyway, so he says. Clint Fowler tried to get me to put a target sight on my M1 (for $150) but I stuck with the GI sight, partly for historical reasons. Clint said that the GI sight looked as a big as a bushel barrel to him who is used to target sights, but it seemed pretty small to me.

    Clint made another comment about peep sights. He said that for those with impaired vision, the smaller peep sight is actually better and will sharpen the vision. Recently, I had an eye test where they swung down a little screen perforated with tiny holes, and through them, the eye chart sharpened up considerably. This must be the same principle although what it is I can’t really say–something to do with the interference of light waves perhaps? Anyway, perhaps this could be a radical new invention. You fit your peep sight with the screen with the tiny holes. FTW? :-)

    Kevin, when the American Guns folks talked about building an avalanche gun I thought of you and wondered if they were in Colorado. So odd that people with a terrible reputation locally turn around and project themselves on the national stage. Well, they had me fairly fooled with their gunsmithing which looked all right from the bit I saw; it certainly seemed ambitious. However, I would have been saved by my repulsion from their personalities. The head guy gets invited into the home of famous hunter and shown his outstanding collection as part of a trade. The Gunsmoke person is explicitly told that a particular rifle is not for sale. But there he goes scheming on camera about how he is going to “separate” the owner from his gun! That would really tick me off–to say the least.

    I was impressed about one thing though. In the course of building the avalanche gun, they do a dye penetrant test to make sure that the metal does not have cracks. This seems like a great idea for surplus guns of the kind that I’m about to send in for a safety check. Is this service commonly available among gunsmiths? Would it make sense to ask for it?

      Matt,

      Wacky Wayne, Kevin, myself and others have been scheming for years on how to separate BB from his USFT rifle. Don’t tell me you’re ticked off at us? :)

      It’s the same action as photography depth of field.

      Since eye exams tend to be done in dim rooms, one’s pupil is rather large. This means you have light rays near the edges which need to be bent at larger angles to achieve focus at the same point.

      When you restrict the light angles to a smaller circle, all the light rays which pass through are more parallel, and need less refraction to come to a point. This also means that light rays from objects at different distances are closer to being parallel, and appear in focus at the same time.

      Without this effect, light rays from varying distances will enter the eye at different angles, and the eye can only adjust to focus the rays from one set of angles. I really wish I could include a sketch

    Large or small aperture? One aspect you left out relates to target shooting, especially at 10m. If your aperture is too small, only a portion of the black bull is visible and there’s no way to determine if you are centered, as all you see is black. Yes, moving your eye closer will help, but there are limits. You need to have both the aperture size and the front sight such that you can see a ring of white about the black bull. Not much is needed, but it much be enough so that your eye can automatically center your aim.

    • B.B. Pelletier Says:

      Gerry,

      You’re referring to the front aperture. I am talking about the rear aperture that you look through. The rear will always be large enough to see the target. I wasn’t referring to a front aperture in this report.

      B.B.

    • Victor Says:

      Gerry,

      Different from prone shooting, where a small aperture works well because of stability, a larger aperture is better for offhand shooting, as in 10 meter competition. It’s really a function of your wobble-area. If you have a lot of motion, and your aperture is too small, then the best you can do is try to catch the shot, which isn’t the way to do things. It’s best to find your natural-point-of-aim, and your best stance (lower body) and hold (upper body), and then shoot to your wobble-area. That means getting the gun to go off without disturbing your sight alignment. So, what you MUST master is perfect sight alignment.

      If you can get the gun to go off without disturbing your sight alignment, then you’re going to do as well as you can, assuming the other body details.

    Great article. If you don’t like shooting with peep sights you either have really bad eyes or weren’t taught how to use them properly.

    An adjustable iris is a wonderful option for shooting with many peep sights. Although B.B. showed one in a picture above he’s apparently keeping this as one of his secrets. ;-)

    I do love aperture sights but something funny happens when I keep both eyes open while I’m aiming at my typical target which is an 8-1/2 x 11 sheet of card with eight 10M air rifle targets printed on it (I use a homemade version of the Archer Airguns silent trap). If I have both eyes open I get confused as to just which of the bullseyes I’m actually aiming at. If I close my left eye, roughly center the target and then open my left eye again I get the improved sight picture you talk about but if I try to make the initial aim with both eyes open I can’t tell which of the bullseyes I’m lining up on. Maybe it’s something to do with being left eye dominant but right handed? (I naturally find myself using my left eye when shooting a pistol). I don’t get this effect with open sights, presumably because they don’t obscure the field of view so much as aperture sights.

    • Victor Says:

      nowhere,

      It is hard to hold both eyes open for the reasons that you sighted, but one of the reasons for wanting both eyes open is so that both eyes get light. So it’s better to use some kind of blinder than it is to close one eye. A patch directly over the eye is just as bad as closing your eye.

      What competitive marksman do with the rear aperture sight, like the one that B.B. shows for his FWB, is they cut out a semi-rectangular piece of plastic, preferably something translucent so that light hits both eyes, and then cut a hole at one end so that it installs where the rear eye-piece screws into the rear sight assembly (i.e., the hole is the same diameter of the rear eye-piece threads that screw into the rear sight assembly).

      Hope that helps.

    • G.Austin Says:

      You need an eye patch or use safety glasses and put sticky tape over the off eye so it cannot focus. Another trick is to read 1 hour a day with an eye patch on your off eye. To weight more to your dominant eye.

      • nowhere Says:

        Thanks! I just tried the suggestions. I wear glasses so I think making a clip on shade might be the easiest. I tried a kluged version of this along with the other ideas and found that a translucent shade over the left lens (lets light through but it’s makes it impossible to focus on the target with that eye) works quite well. Certainly easier than keeping the left eye closed until the target is acquired and then opening it. The shade on the rear sight worked well too. Of course, I’m nearsighted enough that if I had spare pair of glasses that I was willing to remove the left lens from that would probably work too.

        • chuckj Says:

          I mentioned in an earlier blog that I put scotch tape over the off-eye lens of my safety glasses and it works very well.

    • B.B. Pelletier Says:

      nowhere,

      You are doing what I taught Edith to do, and she it right-handed and left-eye dominant. It just sets your brain on the right course, I think.

      B.B.

  • Victor Says:

    If you have good eye-sight, then aperture sights are at least as good as a scope in competition. They give you just the right amount of information. However, the benefit of using a scope is that you can see wind direction and speed with things like grass or mirage.

  • G.Austin Says:

    Great article. I love merit peep sights and mil-spec red dot sights. The 1x magnification really works well training my hand eye coordination.

    Plus peep sights are near indestructible, and very light. You should follow up with a post on recommend peeps for hard recoil springers… Dare I say, maybe the best sighing system for those magnums and rws 34 guns.

  • Johng10 Says:

    Anyone tried shooting field target events with peep sights? I am only near sighted by 1 diopter, but can’t see the kill zones without a scope more than 25 yards away. Would a peep sight with a small aperture make far targets appear bigger?

    • Wulfraed Says:

      There is no target magnification using a peep.

      Target peeps tend to need good light, since the aperture is so small. If you currently wear glasses, take them off, watch a TV from 10-20 feet away, then make an @ with your thumb and fingers — look through the opening at the TV and squeeze the fingers tighter, to make a narrower opening. As the opening narrows, you’ll notice the TV image comes into focus — but also gets dimmer. That is the effect of a target aperture peep sight.

      Battle sights are noticeably larger, though still small enough that night use may be problematic. The apertures on my HK-91 are graduated for 200, 300, and 400 meters — for close range there is a generic V-notch.

      Re: Field Target events with peep sights

      Your bigger problem will be judging distances. You’re relying on your eye alone to determine the variety of distances in Field Target.

      With practice you can determine proper adjustment/clicks for your rear peep sight at various given distances but typically in Field Target you’re not given the distances.

    • B.B. Pelletier Says:

      Johng10,

      I would think it is impossible to shoot field target with a peep sight. FT requires a lot of elevation changing that peeps don’t do well at, plus there is the issue of not being able to see the kill zones.

  • MattC Says:

    Thank you so much for this primer. I have little experience with peep sights in general. However, My Father -in-law and I recently shot his M1 Garand, M1 Carbine, and 1903 Enfield. We were fine at smaller distances but definitely completely innaccurate at greater distances. This primer explains that we were using the sights completely wrong. This will be rectified at our next range session.

    • B.B. Pelletier Says:

      MattC,

      Glad this could be of help. Those are the very weapons where that sort of confusion can lead to errors.

    I have peep sights on my FWB 300S but I think that rifle will shoot well with any sight. I dislike fibre optic sights so much so that I discarded the ones that came with my QB 78 the same day. The new Walther LGV has fibre optics, what a pity! I guess they are cheap so no loss in getting rid of them but it’s a shame to have cheap sights on a top class gun.

  • Mark Says:

    Great article!

    I love aperture sights, but I wear glasses for distance, and notice that with my glasses on the front sight is blurry but the target is sharp. If I take them off, the pin is sharp, but the target is blurry. If the target is contrasty, I can do fine without glasses because I can tell where to put the front sight. What do you guys do about this? Would a smaller diameter rear sight help to focus the target without glasses?

    Thanks much in advance,

    - Mark

    • B.B. Pelletier Says:

      Mark,

      A smaller hole might help, but it also might be impossible for some people to use peep sights because of their prescriptions. It’s a difficult thing to diagnose through this medium.

      I think the thing you need to do is experiment. You can make any peep smaller by covering it and poking a hole through black electrical tape. That should tell you what you need to know about whether you can ever use the peep.

      Please let us know your experience if you try it.

      B.B.

    • chuckj Says:

      To address your peep sight use (and I hope I don’t need corrected here but surely welcome it lest I put out false info) it is better to have a sharp front sight with a blurry target rather than the reverse. From my own experience I find this to be true.

      I am currently practicing with an IZH-46M pistol with rear notch and front post and am experiencing the same issue as you.

      If I can’t focus on the front sight I get a fuzzy and double image of it which makes it very difficult to pick the correct front post image for my sight picture. With my guns with a rear notch and front post it is difficult to get the front post positioned equidistant from both sides of the notch. Every time I blink the image changes driving me to distraction. With a peep the positioning of my eye with the rear sight comes mostly automatic and does not produce a double image of its orifice.

      However, with the front post in focus I do get a blurry target but not a double image of it and it is, with practice, manageable for me to get a reasonable aim point. At first I didn’t think a blurry target would produce good results but I’m finding that it does and gets better with practice.

      Now I concentrate on the front sight primarily as I line things up. I am able to keep 20 pellets inside the black bull of an Olympic pistol target at 10m while standing and shooting off-hand. That’s a 2 1/4″ group which is a good start for me. Although much credit goes to Victor for his invaluable shooting tips that allow me to do this.

      Mark,
      Forgive my poor etiquete as I forgot to address my previous comment to you.

      I also want to clarify my first sentence to say “it is better to have a sharply focused front sight with a blurry target”. I didn’t want that to be misunderstood as a sharp pointed front sight. Although…who knows? Might work.
