If you stick an upper from one company onto the lower of another company, how likely is the thing to work with only the usual level of hassle?
Said another way, can you stick an Armalite upper on a Bushmaster lower? Or a DPMS upper on a Rock River lower, or any other combination?
Do people actually do this, and is it a big hassle?
