Sig Sauer M400

Sig Sauer M400 removes the front sight tower and replaces it with an M1913 railed-front gas block. The M400 provides unparalleled accuracy with a 16-inch chrome-lined phosphate-coated barrel that provides maximum durability and corrosion resistance. A 7075-T6 aircraft-grade aluminum-forged lower receiver adds to the durability and reliability.
