Bushmaster 20 in Post Ban V Match Complete Upper includes bolt, carrier and charging handle. Flat top receiver does not include detachable carry handle. Milled front sight block. I purchased this upper used, so I don't know the round count. Upper is in good to very good shape. $475 plus actual shipping charge. MO or Paypal (+3%).
I have shot a 5 round 5/8" group at 100 yards with South African surplus with this upper.
Thanks for looking!
