That's exactly why I'm confused. An M1a/M14 with a bayonet lug and flash hider meets criteria for AW, but the MA.gov produced FAQ explicitly lists M1a and a weapon substantially like it not. Hurray MA gun laws...
I'm trying to build a CMP Service Rifle/Springfield match legal rifle. The receiver is from Bula. I'm not too attatched to the lug idea but a) it looks weird without it and b) the part I just happen to have currently is a NM reamed flash hider with bayo lug. So I would have to trade it.
