Mil-Spec M4 / AR15 upper receiver with hardware - PREMIUM Square Forge Take-Off


Mil-Spec M4 upper receiver with hardware, Premium

This is a super high quality mil spec M4 / AR15 upper receiver with hardware, but no BCG or chagrining handle.  Charlie's and our friends at Potomac Armory have selected a US manufacturer with exceedingly high standards, ISO 9001 standards, etc.  This OEM manufacturer makes receivers for many other brands from Brass Aluminum forgings (Square Forging).

Quality here is tops.  Compare to Colt, LMT, Daniel Defense.  These uppers came off some of the best made upper receiver groups available, and have not been used.  Some grease on the threads.  Some Cosmoline on the upper to protect it from the elements.
