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 People will rush to defend Colt because they are mIlSpEc but the reality is, "milspec" just means outdated and overpriced to anyone who has served.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.
