Things I liked: Great looking finish, included wrenches.
Things I would have changed: When installed following directions, ramped area on my RWS45 inclined mount above clamping plane. Had to shift mount forward 1/4"+ to allow clamp to engage dovetail. Maybe my old 1985 RWS45 build varies from current models. Will search for different mount.
What others should know: If it fit, would be a great mount . Doesn't work for my old mdl 45. Will put peep sights back on. Solution: ordered an FX Indy PCP . Big Grin!
