It should be but I don' t trust it. I talked to a friend of mine today that has the quick release set up. Although he has not switched the scope from one gun to another he has taken it off of the gun it was mounted on to clean it and then put it back on. He did say that it held it' s zero well. I still would not trust switching it from one gun to another without test firing it. Who knows, it may work. Best thing I can tell you is to give it a try and see what happens.
