I had my first failure to feed with my versamax that i purchased last year. I let my magazine tube go too long without cleaning and the follower was gummed up real bad and the spring was failing to push the shell far enough onto the ramp to trigger it to lift. Just thought I'd throw the information out there. Cleaned gun up. Works fine now. Guess their claim of 2000 rounds without any cleaning and the gun will operate was incorrect.
