Well, I have a tech sight for my 795 that also fit my XT22. It included a front sight that screws on replacing the old and a 3/8" dovetail rear mounted sight. You just screw
This is easy to do.
Originally, I had the stock sights, then I purchased fire sights to get my kids to shoot fixed sights but be able to aim better. I then got a rear williams Peep sights.
So I guess I've tried/played with a variation to experiment.
The Williams rear Peep sight needed LOTS of filing to get it to fit. You have to file to reduce the inner width and file at an angle to get it to fit. That was a pain to do w/o ruining it. The stock front sight was too low to use with that peep sight so I used the front fire sight and still had to file down the back of the elevation ramp.
SOOOO, if you REALLY want peep sights, but don't want to spend $70 for Tech Sights, be prepared to spend almost half that anyway and a bunch of filing.
I don't know if there is a skinner sight that bolts on,but I really wanted some windage control and did not see one when I first looked.
I will tell you this, when I went from the stock sights to the Williams firs sights, my 50 yard groups we cut nearly in half. It was much more repeatable with the aiming. Same thing when going to peep sights, the groups were reduced again. (this is bench shooting). I never compared offhand cause I wanted to quantify the sights and not my offhand stability. I also tried Red Dot which was really easy to aim too and has other aspects as well.
My XT22 is scoped now but I can throw the fixed sights on at any time if I want. I liked the 795 with the tech sights when I had them on, It's scoped but I'll be tossing the tech sights on shortly to do some more indoor offhand 25yd shooting.
If your interested in what williams stuff still, let me know and I'll pull part #'s from my online order history.
