SOLD 5.56 1-7 Twist 16" A2 FS mid gas system with Magpul SL hand guard and Sig Sauer upper receiver (no BCG or CH included). All NEW unfired upper. I did however install a floating hand guard on the upper a while back and scratched it on both sides (type of hand guard that slides over upper) I went a different direction with that build. The photo shows the worst side, the other side is about half the scratch. I have not touched it up and will leave that to the buyer. Barrel is M4 contour 4150 chrome moly with melonite coating. I have a few of these on other uppers. They will shoot right about 1 MOA with 75gr factory loads. $190 shipped, f/f paypal or money order.
