Page 5 - Williams Diopter Sight Reviews

Ease of installation and quality.

Smaller aperture on the peep, I replace with another smaller one that I had.

Much better than the notched rear sights that came on my air rifle.

The price, the design, the positive feel of the knobs.

The finish is a tad shiny... really, there's nothing wrong with this.

It fits my Baikal IZH-61 (And probably, therefore, the IZH-60) perfectly. I have mine set to the lowest mark and it's dead on at 10 meters.

The fit and finish on the sight were fine and it was quickly shipped.

The discription was not very complete and this sight, although it does fit perfectly on my gun, won't adjust low enough to use it with my front sight. There is no way to lower it further so I will have to build up my front sight. An extra aperture with a smaller hole would be a nice extra to have.

Even though this sight may fit your gun, it is not the right sight far all Mendoza rifles, it doesn't have enough downward adjustment and there is no practical way to modify it to work with my gun, a Mendoza/Crosman RM377.

Solid. Durable. Aluminum.

offer different size fittings.

If you put a small grinding stone on a drill and grind the "roof" out above the 2 pincers that grab the gun you can make it fit most guns. Its easy b/c its aluminum.

size,shape, adjustablity

Apeture size. I drilled my unit out and tapped it to fit my match rifle apetures.

excellent sight but too high for most air rifles. Your front sight would have to be really high for this to work. I have the Winchester 1000K and the front sight is almost 1/2 inch too low. If considering this sight observe the height above the scope groove and make sure your current sight is similarly high. I will probably make myself a new front sight as I have the ability to cast one from aluminum.

Fits 11mm dovetail mount. Range of adjustment is excellent.

Perhaps a couple of alternative aperature sizes would be a nice feature.

This is a very well made and accurate sight. Can't be beat for the price!

Good solid hardware used for mounting and adjustment screws permit easy sighting in.

This sight should have an option for a smaller aperture. I think that would tighten the groups up considerably. Elevation adjustment was not sufficient for my springer, but It's not a Mendoza.

Compare prices with a William's or Lyman Diopter and you will quickly
see the value in this sight

Good price for good quality. This is very well made; the windage and elevation knobs click for adjustment, rather than the awkward screws that the low-priced Williams peep I had used.

Unfortunately, this sight will not adjust low enough for any of my springers. Due to the design and size of the base, it sits higher than the "target sights" available. The only solution I can think of is to raise the front sight post.

As someone else mentioned, the base does require a less-common sized allen wrench.
Any rifle with barrel droop may have issues: since the front sight will be low, and since this peep cannot go low enough, shots will be high.

Ease of installation. Crisp click adjustments. Appearance on the gun. It easily aligns with the front sight shroud making it easy to acquire bullseye targets.

This sight needs directional arrows on the adjustment knobs.

No allen wrench came with this sight, and none of mine would fit it. I had to go out a purchase a 9/64 hex wrench.

For what you pay, what you GET is phenomenal. Built solid, nicely finished, well-thought design. It's strong and stable when installed, and it even looks cool.

The photo of the product doesn't show it, but see that hole that's right next to (and slightly left of) the windage adjustment knob? It's the location for a very long stabilizer screw which, unless your sight is adjusted almost all the way up, sticks out like a periscope and compromises the appearance significantly. I would have added at least one other stabilizer screw that's about half the length, and I would have added at least one additional aperture that's smaller than the one it presently comes with.

Other than that, you cannot beat this peep sight for the money...or even twice the money.

the target knobs, micro click adjustments. Full equal of the williams sights for half the money.

only deepen the mounting groove so it can fit more guns.

Installed on a cummings cal 177 now shooting 2in groups at 30 yrd 716fps what more could you ask of a $30.00 beater air rifle. Ill be mounting one on my beeman 1100 s too replace 3x9 scope and laser im currently using. you cant imagine how good this sight is untill you have tried it!!!

Solid construction, no play, firm detents.

Needs clearancing to clear some receiver tubes

The sight frequently doesn't work with factory front sights - it won't go low enough. That issue aside - a wonderful sight to use.

They are well made out of good materials. I bought several on sale. I wish I'd bought twice as many! I intend to install some of these on rimfire guns, too. They will fit wider or more narrow grooves by using longer locking screws or by removing some of the metal where the two-piece bases meet.

I would like a larger area cut away from the sight base above and between the dovetails to fit guns with high, rounded receivers. I don't believe that would impair the ruggedness of this sight and it would increase the number of guns it would fit.

The first one out of the package I screwed ont o a .177 Gamo Hunter 220. Almost fully depressed, it is the perfect height to match the optic fiber front sight for a 50 foot point of aim. This makes it just right for a light springer. It has not loosened after enough shots that I now expect it to stay where it is.

Very well made.

Aperture is huge, .125. Something smaller would be nice.

Sits high. Will probably need a taller front post.
