Well since everyone else is posting their GR-15 Builds, here is the beginning of mine. I just picked up this upper, its a 7.5" Barreled upper with a Yankee Hill Machine Diamond Carbine Length Rail. I was going to wait, but i got a pretty good deal on it. I have a PSA LPK, FDE MOE Grip, Spikes Pistol Buffer Tube Kit, Black & FDE XTM Rail Covers, BAD Lever, Norgon Ambi-Mag Catch, Noveske KX3, Novatac SPL-120 Weapon Light, And a few other parts waiting for me when i get home in a month. Hopefully ill get a chance to pick up my GR-15 in November, so i can start the build. I'm thinking of putting a Primary Arms M3 Clone on it, they have gotten pretty good reviews. Here's a Seek Preview....
