100% authentic, this is a Colt factory Upper that did not make the QA inspection at Charlies for cosmetic reasons
Be careful, there are many fakes out there. Buy from a trusted Source. Charlie's is a Colt authorized dealer, and this part comes from Colt as a spare, or also from a new Colt rifle, for which Charlie's has disassembled.
Factory new or new take-off, Colt upper receiver with Colt CAGE Code marked on the left side, stamped, engraved or dot peened into the side. Some of these are factory new.

Marked M4 in the front, and with M4 feedramps.
This is a blemised item, often with scratches on the top rail, or we have uppers that look like they have been dropped. Graded Medium, rated B to A-. Colt is known for rough handling, but our blems are a little more banged up that you would expect from a new part.
Note: Pics do show specific blems.
