For example, in the picture of the barrel, you will notice a small handling mark. This is true of most Colt and many Knights Armament products that we assemble and/or sell. Expect minor handling marks, as this receiver and RAS are from the military production line, and the US Army, Navy and Marine Corps does not care about aesthetics. Note on military products: Colt and Knights do not use white gloves when handling upper receivers. Charlie's has replaced standard polymer handguards with a new or new old stock Knights Armament RAS. Colt has installed the barrel to the receiver, and the BCG and charging handle, as well as installing the front sight base and the flash hider.
Note: This is a take-off from a full Colt factory rifle. If we are out of stock, as one of Charlie's sales team (either by chat, by phone or email - see Contact Us), we usually reserve a few for customers buying complete uppers or rifles. You can add a KAC vertical grip here, if you wish. The carrier will usually, but not always have a "C" mark, and again, it is sometimes faint, and sometimes not there) Sometimes you will notice a white dot with some sort of paint, which is characteristic of very old and also very new bolts. Often times the bolt is marked "MPC", but sometimes it is very faint.
