Springfield M1A Socom II 308 with Cluster Rail System. Springfield Armory SOCOM rifles are compact, powerful, close-quarter battle rifles. Being chambered for 7.62mm NATO, they still pack plenty of punch to reach out and make that crucial shot at a distance. This Springfield Armory Socom II features a 16-inch barrel (the shortest allowed for a civilian-owned rifle) made possible by a re-tuned gas system. A proprietary, high-efficiency muzzle brake virtually eliminates muzzle rise, enabling you to stay on target for faster, more accurate follow-up shots. The new Cluster Rail System of the SOCOM II further enhances its versatility by accommodating virtually any optic, light or other accessory designed to fit a standard picatinny rail. This example shows little use and comes with one magazine.
