Williams Gun Sight FP-AG Receiver Peep Sight with Target Knobs, Black (14170)

This has fit right onto a number of my springers that have the traditional 11mm dovetails mount. It’s a very high quality sight but requires a screwdriver to loosen the lock screw before you can adjust elevation. I hate that aspect and think it’s ridiculous something this expensive can’t be adjusted just with the knobs. That’s its major downside and with an airgun you tend to adjust the sights a lot in the field.

I own two Diana air rifles, a 34 Classic and a 48. I have this sight on the rear of each and they are fantastic. The issue is your current front sight will approximately 1/8" too short. With the Williams peep sight installed and using your stock front sight your rifle will be shooting high. I have not found a remedy commercially available. You will need to get creative. On my 34, using 1/4" aluminum stock I manufactured a front sight to replace the removable front plastic globe sight. On the 48, using the original front sight, right behind the front blade I drilled a small hole slightly narrower than the front blade. Prior to drilling I purchased a black oxidized allen head screw from Ace. choosing the right size screw and drill and you will not need to tap the hole, just taper the screw before screwing in. The front sigh is made out of very soft metal. After getting the screw in place use a dremel to cut the head off and the screw to length.

I studied long and hard online for this. I sent out several emails to people that rave about thier peep sights but couldn't get a straight answer. I looked at the reviews and descriptions on AOA dot com but was still unsure.I took a chance on this one simply because it is the AG model (duh). Works perfect on my HW30. The airgun has pretty much no droop. The airgun has the replacement inserts in the front sight (I think some older HWs have a fixed front globe sight that is 1/16" shorter than the newer ones). My Williams AG sight is set in the middle of the elevation range.My OEM semi-buckhorn rear sight is very versatile from 10 yards to 100 yards, believe it or not (search for Elmer Keith long range sights for how-to). However, I love the peep sights for 10 yards to 30 yards. 50 yards is a little tricky. Farther than 50 yards is difficult. Of course I'm not hunting, just plinking.I may try the Williams on my HW95 one day. I'd really like to try it out plus I'd like to know if the AG is the right one.The Williams web sight is poor for providing instructions on the AG model. I gleaned little there. Good luck, I hope you are mechanically inclined. That's what it takes. The allen screws tighten the sight to the dovetail on your gun but you have to remove the top half of the sight by raising the elevation (after you loosen the tiny tiny flatheads that lock the Target Knobs). To Mount; First you need to slightly tighten the flathead screw that kinda sets and locks the dovetail clamp. Then tighten the allen screws but don't destroy the wrench. Finally finish tightening the flathead screw.Don't worry too much about mounting the peep sight at extreme rear of rifle. I put mine a convenient distance from the safety for ergonomics. It reduced the potential for maximum sight radius but the sight picture is great. The shorter radius actually eliminated visible light from out / around front globe.

I have this on my CZ 457 Jaguar and Premium, and they fit like a glove on the 11mm dovetail that all 457's come with.I didn't get the allen key that tightens the tiny screws that lock the contraption onto the dovetail. I don't know if they're supposed to come with it, but mine did not. I just so happened to have one that got the job done.The aperture peep hole that comes with this sight is a hunter style, meaning its got a large peep hole. It allows you to see your surroundings a lot easier, but won't give you tight groups, if you intent to use this for bench rest shooting. Luckily, you can order an aperture with a smaller peephole on Williams website.Peep sights, imo, are the way to go. It's much easier on the eyes than the factory AK style iron sights on certain models of the 457. When looking down your rifle, the peep hole itself will naturally go out of focus, acting simply as a window, and your eyes will naturally redirect its focus to the front sight, or target. My aging father with his old eyes cannot shoot the AK style factory iron sights at 50, 25, or 15 yards for that matter, but with the target style aperture peep hole, we are able to run the typical KYL gauntlet at 100 yards.

The sight was what I expected. Fit my Winchester Model 255 without any gunsmithing.

Excellent quality. Fit my Crosman 1701P just right.

maybe I'm being petty, but it would have been nice to have included the very small allen wrench to tighten the sight down, very nice sight and well made

Awesome quality. Bought to replace the plastic rear sight on my Seneca Dragonfly MK2. Aligns to front sight perfectly. Easy to adjust windage and elevation. Highly recommend.
