Lewis Machine and Tool 5.56 Monolithic Rail Platform complete upper in excellent condition. Less than 50 rounds on this makes it as good as new. ASKING 1300. Piston-specific BCG and charging handle included, of course. Shipping shouldn't be too bad on this regionally. I'll probably cover it depending on where it goes, service selected, etc. Trade for Beretta Nano or Mossberg 590 phosphate finish.
