Hey,
I got an Armalite M15A2C 16" midlength mated to a M4 T-marked upper. Can you do an FSB swap for an F-marked FSB? (with taper pins) ar15barrels.com refused, someone on M4Carbine.net (1911rom I believe, who made a FSB drilling jig) also refused and referred me to you. (BTW, I'll presume asking Armalite wouldn't go over very well since they don't do F-marked FSBs (their M15A4s are all flattop gas blocks) and they're swamped so far behind.) |
