Wilson Combat, the best. Bolt Carrier Assembly, 5.56 NATO-Wilson Combat OK, it's only been a few months since we've had to endure the lamination's of our many bros (on many sites, including this very site) repeatedly squealing "OMG, PLEASE SELL ME A BOLT CARRIER GROUP FOR AN AR BUILD I STARTED, ANY ONE WILL DO EVEN FETCH A LOW END PRODUCT RIGHT OUT OF YOUR TOILET AND I'LL PAY $300......NO, $400 FOR IT, AND YOU CAN EVEN LEAVE THE bubblegum ON IT!!! PLEASE PLEASE PLEASE." Very difficult to read that, saw it many times, as I only had one extra Bravo Company BCG all I could do was shake my head and bubblegum on the profiteers charging such outrageous money. I didn't want to sell mine for way more than it should have sold for and then be left without. Even worse than being a profiteer, I kept my BCM, for me. So stock up on this part, cause next go round you can make a couple (OF BIG) bucks selling one for too damned much money. Great deal here. Wilson is having these made for them, not produced in house, but they are known to be the very best, and they are parkerized as well. Great price, great company. I'm buying 2 right now. If you want them later, they are going for $400....each. If you wish to delay the purchase and pay the $400 to me, that's fine, or you can get them right now, right here: $98.57 - which is what I' recommend if you have an AR-15. Astounding price.
