Sig Sauer Model M400 in 5.56 MM Semi Auto Rifle. The Sig Sauer M400 SRP AR-platform tactical rifle features an M1913 railed front gas block instead of a front sight tower. This sight-ready platform (SRP) allows the operator to mount an optic without worrying about the sight tower, and the gas block accepts all iron sights designed to attach onto a Mil-Spec Picatinny rail. This rifle also features a direct-impingement gas operating system with a rotating locking bolt, a 16" chrome-lined and phosphate-coated barrel, and a 7075-T6 aircraft-grade aluminum forged lower receiver. The M400 SRP Classic is designed for use in law enforcement, military operations, and sport/competitive shooting. Upgrades include Magpul Foreend, buttstock, & Ergo Pistol Grips. Includes a 30rd Sig magazine & sling. New in box. Inventory#: D5492.
