Got the supposed repaired/replaced BCG back from BCM last week. I could tell it was the same one I sent back. Apparently their repair was insufficient. Had the same malfunctions multiple times again today when I went to the range to test fire.
Again today I once again tried an LMT BCG and another BCM BCG from another BCM rifle and both functioned in the upper just fine for several (over 100) rounds.
What doesn't make sense however, is I tried the problem BCG in my 16" BCM BHF rifle and it ran fine, albeit for only a mag's worth of rounds.
As a reminder, the upper with the problem BCG is a BCM 12.5 KINO about 450 rounds through it at this point.
For those who know better, why would this BCG work with the 16" and not the 12.5?
