I’ve sent in two pistol scopes. The 3x9 had loose flakes in scope and the 2x7 the front metal piece had popped off. Received them back and about 2 shots later there was flakes in the scope again. The 2x7 had the front metal screwed back on but it was cross threaded so it didn’t sit square with the scope body. That was enough for me. I have sent scopes back to other companies es and gotten excellent results. Ed k
