The standard for bolt carriers


Nothing fancy but this is the standard for bolt carriers, doesn’t have any coatings but it will last a
<br>long time. Anything colt makes rifle wise isn’t cool
<br>Or flashy but it works.

It's a Colt!

Honestly, Colt sucks now. Their products are boring, the machining marks aren't cleaned up like their competitors are, and their quality control is struggling. The one I got came with a bolt that was deformed by the gas rings. It shouldn't affect function theoretically, and it did pass the high pressure test, but it should have failed dimensionally. People will rush to defend Colt because they are mIlSpEc but the reality is, "milspec" just means outdated and overpriced to anyone who has served. And Colt definitely capitalized on the market where the term "military grade" impresses and promotes a cult like following. I wish I could attach a photo to show, but just trust me when I say, there's a good chunk of metal missing where there shouldn't be... and the bolt is the one place where you definitely don't want that.

Only the best to bet your life on


Personally I don’t trust reliability to any company except the original. There’s just something special about running authentic colt parts in a combat ready rifle. Nothing better out there except maybe an LMT lobster claw extractor bolt. But your colt bolt and carrier will serve you many many thousands of rounds. It’s all I will run in my rifles.

“C” marked carrier, MPC on the bolt, and Cage Code on the extractor!


Shipping was quick and cheap. Very happy to receive a carrier with a light dot matrix “C” on the side. The bolt has the MPC mark and the extractor has Colt’s cage code. Everything looks great!

I have 4 Colt bcgs and theyre 100% reliable.Milspec is milspec I can mix and match the parts and theyre still100%.

I wish I had bought more than one.

I regret not buying more than one. Now generic BCGs are this price or more and you are "lucky" to even find one for sale in this price range at all. The Colt name carries a prestige whether deserving or not. If you decide to sell your AR later literally everybody knows Colt and not everyone knows BC etc.
