Mine's never budged over a few thousand shots. I've not taken it off or even checked the set screws. It's just been solid.
Ok, probably a stupid question, but I don't want to mar a nice rifle. It has that alloy muzzle end-piece on it, secured with an allenhead screw. Is that on there solid enough to use that as a cocking handle? I am thinking there might be risk of stripping it off of there, with the allen screw marring the finish.Thanks!
