Lyman Alaskan 2.5 install with 1" Redfield on 1903A4 Clone

These ring reducers work great, but I had to use a heat gun to soften so I could trim excess away. Without the heat gun the delrin was brittel and would chip. But they do work great.

only place that has them

Only place you can find these. Brownells has what you need. I gave 4 stars because of the price of a couple pieces of nylon. If you gotta have them you gotta have them and they are the ONLY company that carries them. thank you Brownell.

Clunky but better than nothing

While I'd rather have dedicated 3/4" scope rings for older .22 rimfire riflescopes, there are very few to none available for some mounting systems. These inserts allow the prevalent 1" rings to be used with the older Weaver, Browning, Bushnell and other 3/4" tube .22 rimfire scopes that look more 'to scale' on smaller .22 rimfire rifles.

Delrin Ring Reducer 1

I have a light weight 1970-80? Tasco widefield 2 to 7 power scope which has outstanding clarity mounted to my Winchester 9422M. I broke the original one piece mount off the scope because the screws had become worn and I wanted a better mount. I didnot realize that nobody makes 7/8" scope tube rings that fit a 3/8" dovetail base. The Delrin Ring Reducer will allow me to use a wide range of 1" mounts.
