I love the way this looks and shoots but it is just too loud for my old ears.
Complete factory upper with M4 handguards, bolt/carrier and charging handle. Excellent or better condition. This setup costs $590 new from Bushmaster. Barrel is marked, "B MP 5.56 NATO 1/9".
I'll trade for a post-ban 16" upper assy. A2 or A3 upper, chrome lined barrel. Prefer Colt or Bushmaster but I'm open to offers.
Pictures available upon request.
