Greetings! Eight year U.S. Army Infantry veteran 1982 to 1990, Panama-Ft Campbell and West Germany . I started putting my LR-308 together in late 2013. It has DPMS upper and lowers, Maten 20 inch medium contoure with RH 1-10 twist barrel, Surefire muzzle brake, CMMG BCG , DPMS standard buffer , DPMS free-float tube, YHM gas block with pop-up front sight, Rifle length gas system, Magpul furniture and the rest you can see from the picture. My best groups with this have been 2cm at 100 meters using Hornady 178 grain Superformance at 2715 FPS and very low velocity varriations. Magazines are Magpul and work great. Last month I switched out the standard buffer for a JP captured spring model and my groups went to hell and had light primer hits. After some anger and confusion I discovered it was a low mass buffer where I needed a heavy model. Solution was to put the standard back in and not be bewildered by "shiny-shiite" again. The two scopes are a Burris AR536 for CQB and an M8 Leupold with aiming dots out to 1000m done by Cheryl at Optical Services Company in New Mexico, I just wish I had access to a real range like I used back in the day going through Ft Campbell's sniper course in 1985. Would appreciate constructive advice and as allways, "RAKKASANS!"
