Things I liked: light weight, the 2 base clamp screws and the recoil pin hole screw
Things I would have changed: allen wrench(too soft) and some of the screw sockets seem to be over size!
What others should know: I used these rings to mount a Charles Daly 2x scope on a Beeman P5 pistol and they wanted to slide. I finally tighten them down then ran the recoil screw down onto the base(the base does not have a recoil pin hole)and they seem to be staying in place.Maybe the wrong rings for a springer pistol!
Things I liked: The sights,super trigger and all around quality!
Things I would have changed: Nothing!
What others should know: It shoots so well with the open sights I have not gotten around to putting a scope on it yet.
