This is my version of the u.R.G I. Its an extra rifle, so looking to sell so I can buy a new watch. Started life as a le6920, everything is colt "C" marked. removed the barrel and replaced with a hodge 14.5 barrel, Installed a geieselle mk16 rail and had a surefire socom muscle device pin and welded to make it 16". Replaced every single small part with Foward Control Designs parts. Have an entire list of them. Asking $3000 with the aim point t1. $2500 without aimpoint T1
