So on my first trip to the range, the paddle of the bolt catch broke on my AR15. Now, before SB281, not exactly good but not that big a deal. But after sb281, what happens if I accidentally break off one of the "ears" when backing out the roll pin? Don't want to be SOL, so I am seriously considering sending it to a 'Smith, just to make sure I still have a lower...I am over thinking/worrying about this???
