Hello,

I’ve gone through several iron peep sight setups trying to find the best for my application. I shoot 25M and 50M and the competitions I shoot allow 4x scoped or iron sights. I have been using an old bolt action Mossberg 46B with aperture sights and found with the round target pips the aperture sights worked as well if not better than a 4x scope.

I bought a nice 10/22T and although it came with a scope I really wanted aperture sights. Since the 22T doesn’t come with any sights it is commonly scoped. However many people still prefer the aperture sights and I have tried several of them out and evaluated them at 25 and 50M ranges. You mileage may vary, but here are my results.

I wanted to make sure each sight could bottom out below 25M and adjust to 100M. I tried using the front post sights that came with the Tech-Sights units and found the best results when lollipopping the target pips, but the Lyman front apertures provided a naturally better sight picture. This is especially more accurate to those of us with aging eyes…. Those little pips sight easier in the round apertures than on the top of a post. I also did not want to have a front sight band adding weight to the rifle, so I had 3/8 dovetails cut in the rifles I was testing. (Russian Biathalon Basic and 10/22T)

If you do not want to have dovetails cut, you can use a barrel band and mounting base, you will just need a sight that uses a front to back dovetail.

DPMS Detachable Rear Sight

The DMPS sight was familiar to me and it’s adjustments familiar as they would be to anyone else that’s been in the Army. It gets good marks for the clickable adjustments and familiarity. This sight was too high to be able to get zeroed at 25M even with the tall Lyman globe sight.



Tech Sights TSR200

This is the go-to sight for many .22 users. It did require the tall Lyman globe sight to hit below 25M. (The included front post is the proper height of course). If you were in the Army very long ago, you will be familiar with the windage adjustment on the rear, and the vertical front post adjustment and the nifty little tool needed to make the adjustments easy. All around I liked this sight, but found the vertical adjustments a little too difficult. That tiny little vertical wheel is hard to turn and easy to scratch up while you try to adjust it. There’s also no vertical visual cue on the sight to mark your zeroed ranges at. It precludes using a rail for a scope.

Williams WGRS-RU22

This sight screws right into the receiver and is an OK sight but has a few drawbacks. First, the adjustments are not click-able, and you often lose where the sight ‘was’ when you loosen the set screws to make adjustments. Once you loosen those screws, you can accidentally tap the sight off sight with no reference to get it back to. It also precludes using a rail if you want to swap back and forth with a scope. The plus points are that it can accept different Williams apertures, is small, and will use the short regular Lyman front globe. Also comes with the Firesight front post.



Tech Sights TSM200

This is my second place choice. It would NOT fit on the stock 10/22T rail though. However it worked just fine on the Weaver T0-9 rail which is properly drilled and provides the screws for attachment to the stock 10/22 receiver holes. Tech Sights markets this as their Marlin 60 & 795 sight, and it’s a bit shorter than their TSR200. I do like the clickable adjustments that hold firm, but the drawback is the vertical adjustment is difficult with that little tiny wheel. They have since added a tool available on their website for making this adjustment easier.





Williams FP-AG Receiver Peep Sight

This turned out to be my favorite of the lot. It has EASY click-able vertical and windage adjustments, mounts to the T0-9 rail and larger rails with locking mounting screws. A simple little screwdriver will click right through the adjustments and there are scales marked on the sight for vertical and windage reference. Fits right around the 10/22 receiver and no stock inletting was required. I replaced it’s stock aperture with a larger disk that has a smaller hole. Williams has apertures in several sizes and hole diameters.

So the recipe for my favorite final setup is as follows:
