Colt M4 Upper Receiver, "C" marked (stamped) NOS


Colt M4 Upper Receiver, "C" marked (stamped)

Factory new (old stock), Colt upper receiver with "C" marked on the left side, stamped or engraved into the side.  This is factory new.  Most are take-offs from new guns or upper receiver groups.  Some are purchased as a part. Most have world famous Colt oil on them.  Inside has a gray dry lube finish.  Marked M4 in the front, and with M4 feedramps.

The Colt upper receivers are not made with a "C" mark anymore, so if you are looking for a great clone build project, this is what you want.

Note:  Colt has used, and continues to use a number of original forgings.  These forging marks have the appearance of either a raised square, a raised keyhole, or a raised A with broken arches.  All are 100% legitimate, and your 100% Colt upper will have one of these marks.  We do not separate by forging marks, and do not take requests for forging marks as part of our normal sales process, as it just requires too much handling and manual intervention. If this is very important to you, please inquire first about special handling.

Note:  With this Colt product, or any Colt product, expect some handling marks, oil, occasional small scratches or anodizing colors that vary.  Colt is made for battle, and in the factory, Colt parts are not treated with kid gloves.  A minor imperfection with a new or NOS Colt product is not a defect.

includes dust cover assembly and forward assist assembly.  No BCG or charging handle.
