i bought a new DPMS panther lite 16 about 3 months ago and shot it for the first time today, i have never shot an AR before and am pretty pleased with it so far. It functioned flawlessly except for one failure to feed but that was due to a surplus magazine i bought online, overall a great weapon i did noticed and odd occurrence though, i was shooting from 37 yards havent touched the sights ever and it shot a 3 inch group using wolf 62gr fmj, is it possible that the rifle was sighted in from factory?
