Selling a Bushmaster A1 upper receiver. This is a “Special Order” one that has M4 feedramps. I had it on my Spike’s 14.5" “M4” and never had a hiccup. It has a few rub marks on it/chipped anodizing(Please look at picture’s carefully) The threads also have some anodizing loss, but the threads are perfect.
Selling this because I got a good deal on a Acog. And I bought a flat top instead of mounting it on the carry handle.
Asking $100shipped. USPS MO, or Paypal+4%
