Description
Sig Sauer M400 Forge Features The Sig Sauer M400 Forge in Moss Green Cerakote blends premium performance with a field-ready finish built to withstand the elements. The 16 cold hammer forged steel barrel with FNC finish maintains consistent accuracy and resists wear through extended use in demanding conditions. A mid-length gas system manages the recoil impulse effectively keeping the muzzle flat and follow-up shots on target. The 15 M-LOK handguard offers a lightweight modular platform for mounting accessories along the full Picatinny rail without adding unnecessary bulk. As a well-appointed 5.56 AR-15 rifle the M400 Forge pairs the Moss Green Cerakote aesthetic with a TriggerTech 3.5-pound two-stage flat blade duty trigger engineered for a clean consistent break. The 6-position Magpul SL-K stock and ambidextrous charging handle round out a rifle that performs as sharply as it looks in the field.
