Long story short- trying to refurbish 20 year old agency owned M16A2 Commandos (full auto). The lowers are in reasonable shape and will be fine with new springs. The uppers are unfortunately pretty wasted and in need of essentially complete replacement. Bolt carriers are salvageable, but everything else is pretty much toast. Back in March, our sales rep for the regional Colt distributor quoted and sold us 6933 EPR uppers, which are 11.5” government profile barrel, 10.5” Centurion M-Lok hand guards, and complete BCG.
Fast forward to today and I found out they are unable to fill the order as apparently Colt quit/never made these as uppers. It looks like they still make complete 6933 EPR guns, but not uppers. The sales rep wants to look into LWRC (which I thought was primarily big $ pistons or proprietary pattern DI), or Sig (which I’m hesitant of because Sig). Anyone have ideas for equivalent complete uppers? Must be mil-spec or better and due to budgeting cycle, similar or lower price (mid $600 agency price).
