Will a Bushmaster lower fit on a Colt upper or will a Colt lower fit on a Bushmaster upper?

It depends.....

The front pivot pin on certain Colt uppers and lowers is a larger diameter than the standard. So if you buy a large hole Colt upper, it will not mate with a Bushmaster lower and vice versa (large hole colt lower mated to a small hole bushy upper).

HOWEVER! They make aftermarket pivot pins that allow you to have dissimilar hole diameters. I don't recommend them tho, as they make it a PITA to breakdown your rifle.

The best advice is to make sure you clarify the hole diameter with whomever your are buying parts.
