Update Your Vintage Rimfire With Optics Of Choice
Weaver-style rail conforms to receiver curvature and attaches to existing mounting holes, centering any diameter scope directly over the barrel. Lets you mount full-size scopes and red-dot optics. Provides enough clearance to keep original rear sights in place. Easy installation: remove bolt cover, if present, to allow bolt to clear mount; add rings and scope of choice.
