Things I liked:I put these rings on my crosman 1400 .22 pellet rifle and they work great. used with Air Venturi intermount rail. Very solid. Things I would have changed:A little high on the gun, but no big deal.
Things I liked:Used this to mount a scope on my crosman 1400 .22 air rifle. I used the weaver centerpoint 1" rings for the scope. The two work great together. This is the only product that I found that works on this old air gun What others should know:You have to take off the end plate on the barrel and the action bolt handle then tap the base rings onto the barrel. They are tight and scratched the barrel slightly, but not really an issue because the barrel was slightly etched from years of service anyway.
