The Sig Sauer M400 Forge in Concrete Gray Cerakote brings the same premium engineering as the standard platform with a hardened, corrosion-resistant finish that performs as well as it looks. The 16″ cold hammer forged steel barrel with FNC finish ensures long-term accuracy and durability under sustained use. The mid-length gas system smooths out the recoil impulse, keeping the rifle flat and controllable through rapid strings of fire.
A 15″ M-LOK handguard with full Picatinny rail keeps the setup modular and lightweight while leaving room for any accessories the shooter requires. The 5.56 AR-15 rifle platform shines here with a TriggerTech 3.5-pound two-stage flat blade duty trigger that delivers a crisp, repeatable break shot after shot. The 6-position Magpul SL-K stock and ambidextrous charging handle round out a build that fits any shooter right out of the box.
