BM 16" HBAR. Functions flawlessly on XM193/Q3131A/Wolf. About 1000 rounds through it so far. Problem: I have noticed a moderate wear spot on the inside of the upper. The spot is oppsite the ejection port, just behind a cut-out I assume is for the cam pin to function, just below the channel that the charging handle functions through. The bolt carrier/base of the gas key/cam pin also seem to have some wear on them where they would possibly rub this area. I would describe the wear as a little more than peening. Is this regular break in? |
