remaining month, there was a sale on Colt 6921 uppers. due to the fact that I completely don’tr need any further AR uppers, I bought one anyhow.
The Colt 6921 higher is a 14.5 inch executive profile M4 upper. Your lavatory ordinary M4 upper. no longer to be incorrect for the 6921HB or SOCOM mannequin, which has a heavier profile barrel (.75 inch with M203 cuts).
It comes in a nice box, and it includes a Colt AR15 guide.
The decal on the aspect suggests that this is half number SP401165.
The higher is available in a bag that’s designed to avoid rust. It additionally comes with a wick in the barrel.
This specific upper does not include a charging address or bolt provider group. also there is no side sling swivel included.
I wasn’t going to publish about this plane jane upper, but then I be aware there are these weirdos out there who care about stamps, marks, and so forth. I figured I should still publish it up for reference. I acquired this higher from Brownells in Dec 2020.
now and again I read about someone getting a new upper and complaining that the finish is defective and gray on the interior. No, it really is dry film lube.
The front of the upper receiver is M4 marked, however i was unable to get a transparent photo of it.
