When I first noticed the problem it was right after i had put a holo sight on it...i thought, "I wonder if they did something dumb like used screws that were too long?" But then I thought, na, they would have to know better than that. For curiosity sake I took the bushnell and the mounts off....action worked normally. So I took it back to the local sporting goods store and let them know what they did. They filled down the screws and apologized. I wish there was one local guy that knew what he was doing. The local gander mountain gunsmith is a jerk, worried only about what time he's gonna get home; and the rest have their moments too. Very irritating situation.
