A couple guys I know opened a gun shop where I'm from. They specialize in building tactical rifles and selling all sorts of tactical gear. I let them build a rifle for me. Here is what I built: Spikes Tactical Lower YHM Upper YHM Fluted Barrel (1:7 twist) YHM Rifle Length Diamond Forearm BCM Gunfighter charging handle Surefire Nitrolon Light with VLTOR mount Foregrip with pressure switch Eotech 551 Magpul MBUS Front & Rear Magpul MOE Grip Magpul CTR Stock Magpul Trigger Guard Magpul ASAP Plate with MS2 Sling Magpul Rail Covers I think that the rifle came out very good. Haven't had a chance to bring it to the range yet, but I will within the next week or so. The name of the shop is Allstar Tactical, check them out on Facebook. You can see pics of their other work.
