I recently bought a new completely stock DPMS lr260 remington 24"bull barrel 1-8.5 twist put a vortex viper 6.5-20x50 on it shot my first group this weekend with it. After a few adjustments I was on target manged to shoot a 3 shot 5/8 inch group at 100 yards also managed a .38 outside to out side 3 shot group at 100yds all shots were sand bagged and I was shooting federal 120 grain balistic tips. Looking for trigger replacment soon as its terrible. All in all the rifle shot a lot better than I thought but still needs improvement
