Might as well start the thread. Starting off with this franken-rifle that is now mostly finished. Re-barreled an old Colt 6920 LEA trade-in with a Geissele 14.5" Super Duty barrel that has a pinned & welded Huxwrx flash hider. Installed a Mk16 URGI rail. Still trying to decide what optic I want on it, either the Aimpoint, a EoTech, or a Brownells MPO that I have sitting around. The stock on it is going to be gone when I get either a Magpul CTR or UBR at Oaks this upcoming weekend.
