Great looking but there are a few nitpicks - Ruger Weaver-Style Scope Base Adapter for Mark I, II, III Pistols 90224

Great looking scope that shows exceptional quality. Perfect if you plan to never remove your scope. Though as a design decision all the rail grooves are rounded instead of squared. If you have scope rings that have square indexes then they won't work with this rail. Secondly, the spacing of the grooves doesnt match the picatinny standard, which means you'll need to move your scopes back and forth if you're moving scopes around.
