Re: Rem XR100 action compatibility?
Yes, it is basicly an aluminum sleeve if you will that supports the barrel and the action. it is bedded, (mine is pillar bedded), in the stock. the block is the only contact with the stock. It supports the heavy barrel with the action hanging on for the ride. This is a simplification. If you contact me i will send pics of mine. I ain't up on posting on forums. Also the beauty of it is you can have your smith make you any barrel you wish onn the same platform and you can change them yourself. (ie, .308,6br,.As long as they are short action.)
