Not too sure how long this version on a retro AR has been out. Price wise it seems to be a few bucks less than the Brownells version of the BRN-16A1. It seems to be built more like a Canadian C7 version AR than a retro rifle pre se, but it’s what they made.
According to the description, it has a brass deflector, so it's a C7 upper.
