Gentlemen, what's the difference between a full/auto BCG and a semi/auto BCG? I don't see a difference looking at pictures and I can't afford to buy something I can't use.
The reason I ask is that I figure that something designed to run 16 rounds per second has to be a tough piece of goods and should last forever in a semi/auto.
I hope this isn't a newbee type of question. I've been a shooter for almost half a century but I'm new to the AR platform.
