A short M1A variant offered by Springfield Armory. It has a 16” barrel, hence the name. Equipped with an effective muzzle brake, it has fairly mild recoil and much easier to handle in tight spaces or dense brush. The front sights on these are actually wider than regular M1A front sights, which some owners blame for poor accuracy when using the iron sights. The SOCOM 16 has a tactical version in the SOCOM II.
My next rifle will be a SOCOM 16.
