I am experiencing a problem with my ranch rifle, that I'd like some help figuring out. When I'm shooting my rifle, usually after the first couple of 20-round mags hve been fired, the trigger guard will pop up just enough that the trigger will not operate. I don't think I'm actually popping it up on my own, but it seems that the firing action gets it to pop out of the slot. Seems like the trigger guard is just "opened" up enough that its not a really tight fit for the spot it hooks in to. I'm tempted to try to bend the guard a little more so that it's tighter, but thought I'd check the forum to see if anyone else has had this issue, or if I am somehow doing something wrong. I've had this rifle more than a year and run > 1000 rounds through it. Otherwise its operation is awesome.
