My daughter has a Mini-14 she has put about 600 rounds through with no problem. The other day at the range, the trigger group popped out while she was firing. We put it back in and I fired 5 rounds through it. She reloaded and after 3 or 4 rounds it popped out again. I can't see anything wrong, but I don't know enough about this rifle to tell. Any ideas?

how is the lockup on it?.... if it doesn't lock up and clasp tight it will come out.

The lockup is fine. That's why I can't figure out why it's popping out. I'm wondering if the after-market magazine may be causing it, but then she hasn't had any problems before.
