By Matthew from USA on 2008-06-21 21:22:05 Things I liked:Fits 11mm dovetail mount. Range of adjustment is excellent.Things I would have changed:Perhaps a couple of alternative aperature sizes would be a nice feature. What others should know:This is a very well made and accurate sight. Can't be beat for the price! |  |

By Neal from USA on 2013-03-19 08:34:13 Things I liked:Fits the RWS 48 very well.Things I would have changed:I don't like the sight adjustment. It requires loosening screws to adjust. It would be a much better product if it had screws that "clicked" without the need to loosening the screws the hold it in place. The horizontal adjustment has some issues. The tang the screws hold down is not long enough. What others should know:I would pay more for a better sight. |

- Things I liked:All solid steel, well made, rugged and stays on setting.
Things I would have changed:Make it easier to change settings in the field. Something like adjustment knobs. You have to have two screwdrivers, and once you loosen the set screws the parts and/or screws can fall off. Good luck finding them in the grass. For windage adjustment, loosen 2 screws and shove the peep over and retighten. There are adjustment marks on the bridge but no corresponding mark on the peep, so you have to guess how far you moved it. The elevation adjustment has corresponding marks but the hole wasn't tapped all the way through so the screw would not raise the peep.
What others should know:I got this sight on my new Air Venturi Bronco Target Pro, and while it can be made to work, and actually work very well, the sight will not adjust low enough for the Bronco front sight. It happens that Pyramid Air sells front sight spacers (PY-A-4182, 4 for $7.35)for this rifle. - Things I liked:The scope that came with my Crosman 1000X would not hold zero and the Williams diopter was an excellent quick fix, and well worth the money. Accuracy from the bench at 33 feet is equal to that of the scope's during the few brief instances when it held zero.
Things I would have changed:Wider slots on the elevation and windage locking screws. A smaller apperture and a reference mark on the sliding apperture ramp to facilitate windage adustments. An additional locking screw for the dove tail groove.
What others should know:Most shooters, myself included, have a tendancy, when shooting off-hand, to chase the crosshairs; a little wobble leading to a cycle of increased wobbling, finally ending in a jerked trigger. Wobble is less evident with a diopter and they are a joy to use when shooting off-hand. Rear apperture sights are vastly under-rated. Diopters with a relatively small apperture are a boon to older shooters. They will really sharpen a sight picture. I am 76 and near-sighted. I use a Meritt adjustable apperture and a Lyman 48 sight on my 03A3 Springfield, and have shot many sub-MOA, five-shot, 100 yard groups from the bench. I now switch the Meritt to the Crosman when I'm not shooting the 03A3. It's too bad Williams doesn't make a FP sight for air rifles. - Things I liked:adjustable, sturdy
Things I would have changed:nothing
What others should know:if u dont wanna pay extra 50 for adjustable knobs, dont! perfectly fine without it - Things I liked:very well made
Things I would have changed:none
What others should know:I've been using williams receiver sight on both rimfire and centerfire rifles .The sight holds the adjustments very well even on heavy recoil rifles should even better on an air rifle(my first time using it on an air rifle. - Things I liked:Well made as all Williams stuff is. Lots of adjustment.
Things I would have changed:This sight is huge. Could have been made a little more compact. - Things I liked:Dimention, especially the height is perfect for RWS 350 Magnum with the original front iron sight. So far, this is the only sight solution worked for my RWS 350 Magnum, which has ruined quite a few rifle scopes, from the combo scope to some name brand stuff. Of course, if there is one ultimate scope will finally work for RWS 350 Magnum somewhere out there, I will try to get one. ------ The original front iron sight with this wiliams diopter rear sight create a very good aiming radius, but it is still no match to optical scope.
Things I would have changed:Maybe come with different diopter sizes.
What others should know:For magnum airgun, you may need a recoil stopper. Currently, I am using the big screw head as a recoil stop pin, which is not strong enough for a scope mount (too big a mass), but strong enough for this diopter sight (small mass). - Things I liked:Very accurate once dialed-in with a spring air rifle.
Things I would have changed:Thin the bottom of the upper arm, to be usable with Crosman 13xx (with steel breech upgrade). - Things I liked:Very accurate with my Winchester 1029S rifle in my basement shooting range (20-foot) with numerous same hole shots.
Things I would have changed:Thin-out the underside of the upper arm so that it could be used with a Crosman 13xx that has had the steel breech upgrade. Use higher-quality set screws (one split the first-time it was used; it is still usable but must be carefully tightened first).
What others should know:Unmodified, this will not work with Crosman 13xx pistols that have the steel breech upgrade (the elevation is too high; even with a custom Michael Chavka barrel band). - Things I liked:A nice Williams aperture at a bargain price relative to other Williams apertures.
Things I would have changed:Perhaps for a few bucks more add a second aperture sized 0.50" to satisfy target shooters.
What others should know:This is my third Williams sight, but my first one for an airgun. Because of that I have a selection of Williams apertures that fit right in this rear sight. A 0.50" aperture works really well with good lighting in a target shooting environment. However, the standard aperture that comes with this Williams "Diopter" sight is perfect for lower light and shooting in the woods. Basically, than means the standard aperture is just right for hunting and plinking. - Things I liked:Very nice sight. I surrounded mine with a thin layering of tru-glo for night shooting. Adjusts for windage easily and reliably, and replaces the less-than-reliable gamo silent cat's rear sight aptly.
Things I would have changed:If this was $5 cheaper, it'd probably be the best deal on this site.
What others should know:If you want a reliable rear dovetail for a target rifle/pistol, hop on this. I've been using mine on a gamo silent cat, and it withstands the heavy spring vibration without any adjustments necessary. - Things I liked:I ordered two of these - one for my Bronco ( along with the front riser kit ) and one for my son's IZH-61. Mounting was easy and fast, no problems at all, Quality seems fine. I have a huge selection of hex wrenches, but a lot of people probably don't, so they'll require a trip to the hardware store.
What others should know:I'm guessing that the sight has changed very recently - earlier reviews indicated that the aperture was friction fit. That is NOT the case with the ones we bought - they're threaded, and a Williams .050 replacement aperture screws in just fine! - Things I liked:Tightens snugly in the dovetail, but the two bolts are a very non-standard size. Very positive clicks for both windage and elevation.
Things I would have changed:Make standard size allen bolts for mounting, or supply the wrench...I had to visit several hardware stores to find a wrench that fit.
What others should know:The first sight received was very thickly and poorly painted, and the aperture was very wiggly. Pyramyd replaced it and the new sight has a very steady aperture and appeared to be blued, rather than thick paint. - Things I liked:Precise, economical, lightweight, right size aperture for me, seems durable.
Things I would have changed:The clamp is too shallow, requiring fitting on some rifles. A choice of diopters would be nice. Allen wrenches to fit the two screw sizes would also be considerate.
What others should know:Aperture sights are both fast and accurate to the limit of air-gun hunting ranges. They are superior to optical sights in many ways (simplicity, durability, low fiddle-factor, weight, profile), but require practice, whereas optical sights "seem" like an instant solution. (They are not, but that is another story.) The first mistake new aperture users make is to try to use a small aperture and to consciously try to center the front sight. The proper technique is to ignore a large aperture and look only at the front sight. Aiming takes care of itself. Not magic, but feels that way sometimes. - Things I liked:Easy to mount. It fits my Diana 34P well. It is cheaper and much more rugged than the replacement factory sight which I broke the first day I had my gun.
Things I would have changed:Appeture is much too large.
What others should know:This is not a sight for high accuracy. The design of the sight lends itself to 1" groups at 20yds at best due to the "slop" of an appeture sight. That could be improved with a smaller appeture, but overall these types of sights are not very accurate.CommentsBy Vick from USA on 2012-04-24 0 
See review by Vick - Things I liked:The Mendoza appears to be very well made and very sturdy. The click adjustments work well. I like the method of clamping onto a rifle as it allows a wide tolerance for groove width (unlike the Williams Guide #54).
Things I would have changed:The aperture is very large. I prefer smaller, so I would like to see the aperture threaded, not pressed in. This would allow easy replacement. The minimum heigth is to tall. I can zero with the top of the front sight hood on my TF99P (not the front bead). Could they mount the aperture below the bridge instead of above it?
What others should know:Despite the issues, with my old eyes I can shoot better with the Mendoza than with the open sights (which are very good on the Tech Force 99P). - Things I liked:For the price a good value. Easy to install on my t01 rws 48.
Things I would have changed:Instructions with the sight pariculary barrel droop issues and need to raise the front sight.
What others should know:As reported elsewhere, many schooters will need to raise their front sight to compensate for the high position of the Mendoza. I ground down the front sight and used electrical tape to attach a piece of foam. I then stuck a hat pin in the foam making a sight post. It worked but looks ugly! Ideally a machinest should be able to make a dovetail ramp to which you can epoxy the front sight of your choice. How high the ramp? Experiment with the foam's thickness. - Things I liked:easy mount and knobs for adjusting. simpler and more efficient then the similar Williams sight.
Things I would have changed:add optional eyepieces in different sizes - Things I liked:Nice to hit something without a scope.. I love this thing..
Things I would have changed:Should have a few different eye pieces for it.CommentsBy Michael from USA on 2012-01-14 0 I understand that Williams peep inserts fit. - Things I liked:Excellent machine work, tight, precision fitting parts. mounted easily on my Beeman S1 break barel 11mm grooves. Click stops soild and do not move once in place. Sadly, though, I had to return it because my front aperture sight was not high enough to sight the air rifle in.
Things I would have changed:Change nothing.
What others should know:You will love this aperture sight. Price is an absolute bargain. - 12
