The AR-10 is slightly larger and heavier than the AR-15. It was originally designed to chamber the military 7.62x51 NATO cartridge (also .308), which has a COAL of 2.800" (71.12mm) 45 Raptor , uses the standard 7.62 NATO case, cut to a length of 1.800" from 2.015", resulting in a straight-wall cartridge, neck is sized to 0.452".
