The Picatinny scope mount designed for the Savage B17 & B22 series rimfire rifles with factory drilled receivers. Works great when using Picatinny and Weaver style rings on those really long, large objective high powered scopes. Made from billet aircraft aluminum and then black hard coat anodized for a long lasting finish. The ejection port area is "cut-out" for easier, cleaning, single shot loading or clearing a stuck spent case.
5MOA built in to the mount to allow most scopes to be "zeroed" anywhere from 25-150yrds using 22LR target or subsonic ammunition
