Nickel boron bolt carrier group. - TRYBE Defense Mil-Spec AR-15 .223/5.56/.300 AAC Complete Bolt Carrier Group (BCG) BCG

I was looking for a decently Priced. nickel Boron Bolt carrier group. This one caught my eye and after reading the reviews I thought I'd take a chance. It did come in a plastic bag not quite what you would expect from a major name manufacturer. But they're getting it and it cost me an armor leg like the ones that I Usually by. So far I've only physically ran into my upper receiver and make sure it locks up well in my barrel. It seems good. We'll take it to the range and put some 300 block out through it after the rain stop.
