Just got it back from adco. New centurion hammer forged 16 inch middy barrel with a KAC folding front sight gas block kit. $750 shipped PMO. Will throw in a modded 11 inch larue rail that has a front sight cut out for $150. PM me your email for pics. Thanks.
Also interested in trading for Trijicon optics, aimpoint 3x magnifier in Larue flip + cash, aimpoint t-1 in larue tall + cash, or centurion arms 14.5 inch middy barrel with pinned front sight post + cash.
I just got and installed a Vltor mur upper with forward assist and black moe handguards. I will sell this as a semi complete upper for $900.
