Colt M16/AR15 Complete Bolt Carrier Group Assembly

I have put a few hundred rounds through my gun with this carrier and have had no malfunctions (bolt sticking like others have said). Also, the bolt is marked MPC and the carrier IS marked with the C.

I found this BCG on arms unlimited at a better price than any other place. Also, the fact that it's a Colt BCG means they carry excellent products. "mpc" stamped on the bolt and "C" stamped on the carrier = authentic. Expedient delivery too

Everyone else did not have, arms unlimited did and they beat most everyone's price.

EXACTLY the same as the one that came in my M4. Always wanted a spare to keep on hand and now I have one from Colt. The price is less than some and not much more than a middle-of-the-road product.

no guesses or worries as to quality, and they have it.

It might not be pretty and shiny, but this thing just works. Great fit and performance. Just what I expect from Colt.

I had expressed doubts in a previous review about the BCG - whether it was Colt. Since then, I did get a positive representation from AU that it was a Colt. I re-examined the bolt. Though faint, the "MPC" IS "pinged" into the bolt (like a dot-matrix printer). With better lighting I was able to confirm that it wasn't merely stamped. This doesn't necessarily prove anything, but now makes the bolt consistent with my other Colt bolts, unlike my previous observation. But the one feature that was the best evidence to Colt manufacturing was the staking of the gas key. It is identical to the other BCs: a solid, conspicuous, and deep staking. So, though lacking the "C" on the BC, a second look now has adequately rebutted my earlier misgivings.

I bought this Colt BCG as a spare for my 6920. The ordering process was fast and simple. The BCG fit and functioned just like the one that came with my Colt rifle. The gas key is well staked, the bolt to carrier fit is nice and tight. AU's fast service is great, and the price is right for a genuine Colt Bolt Carrier group.

Super fast shipping! Arms Unlimited is top notch. However, when I received my Colt BCG, upon inspection, I found that while the Bolt has the "MPC" stamp (albeit, it is very faint) the Bolt Carrier is missing the "C" stamp that consumers expect from Colt. I'm sure this is a legit Colt Bolt Carrier Group Assembly, and AU has assured me that it is indeed 100% Colt.
