Hi everyone,
I have a 10.5 GM barrel (5.56) with a .87 gas port size. Is anyone running this barrel I've used an H and H2 buffer with car buffer spring.
300 rounds in and the bcg rides the round from mid-shell and jams it upward , bends it, and leaves bolt lug marks on the brass casing. Do I need H3 buffer and or x-power buffer spring?
Note: I've tried another bcg and different mags
With same results. Brass is ejecting at
1 o'clock area, some fly far some don't
Thank you
