Q
Ken, guest, from MN, United States, asked on March 04, 2019

Will this be "C" stamped? Also, which forge markings do these have?

A
Answered by Drew Austin, member, from VA, United States, on April 01, 2019

No, there are no Colt proof marks on this upper. The forge marking is a Square (Brass Aluminum Forging Enterprises). Save your money can get a real Colt upper if you're after the markings.
