Springfield AA9611: Springfield Armory\'s M1A Socom starts with a specially-engineered 16 inch barrel that is mated to the gas system with a proprietary muzzle brake. The muzzle brake reduces felt recoil and keeps muzzle rise so flat that follow-up shots with a caliber this powerful have never been so easy. It comes with enlarged ghost ring aperture rear sight and XS Sights Tritium Insert in the front sight which gives you the quick target acquisition capability you want and need under any conditions. It features a forward scout-style Picatinny mount, one 10 round Parkerized steel magazine, and comes with a custom ballistic nylon case.
