Be wary of BCG’s with limited descriptions. These are our premium BCG’s. Made right here in the U.S.A. and done right. Our manufacturer uses a stronger than milspec 9310 alloy for the bolt, and an 8620 steel for the carrier. If for any reason you are unsatisfied, or you have an issue, just return it within 90 days of purchase for a full refund or exchange. Don’t settle for a BCG with shadowy specs. These come to us straight from the manufacturer, so you can be confident in what you are getting. Inventory is accurate and updates every second.

  1. 2 out of 5

    Maybe the new ones are better but the one I purchased a year ago was giving me some major ejection issues. I had a few FTE’s and my receiver would be full of brass shavings from violent extraction. This was still the case using an adjustable gas system

    I’ve used several of these and all worked as advertised. I have one with over 15k rounds on it and it still runs like a champ. I replaced the extractor spring/insert at approx 10k just to be proactive.

    9000+ rounds and still runs great. Dirty as h€!! though 😉
