AR-15 bolt on M16 lower
I'm working a deal on an M16 lower, which comes with a 20-inch A1 upper. As much as I love retro guns, I plan on using the uppers I already have for my SBR.
Will I be able to slap these uppers with AR-15 bolts in them on the M16 and have them run full-auto with the M16 lower, or will I need to get an M16 BCG?
I've found plenty of info on M16 bolts in AR-15s, but nothing on AR-15 bolts in M16s.
