1) What's the difference between a M16 bolt carrier group and an AR15 BCG?
2) Is one 'better'?
3) Do NFA rules apply? In other words, is it legal to put a M16 BCG into a semi-auto AR15?

I probably should've done a search first.

1. A little extra meat on the back to trip the auto sear on M16 BC.
2. No
3. Yes it's legal as long as no FA trigger parts.
