PRODUCT DESCRIPTION

The SIG Sauer M400 Forge FDE is a semi-automatic, AR-15 style rifle chambered in 5.56 NATO, featuring a Flat Dark Earth finish on the receiver and a factory-installed ROMEO-MSR Gen II 2 MOA red dot optic. It is built around a 16-inch cold hammer forged steel barrel with a mid-length direct impingement gas system, offering a balance of durability and performance. The rifle includes a 30-round detachable magazine, a TriggerTech 3.5-pound two-stage flat blade duty trigger, a free-floating 15-inch M-LOK handguard with full-length Picatinny top rail, an ambidextrous charging handle, and a 6-position MAGPUL SL-K adjustable stock with a black reduced-angle polymer grip. The barrel has a 1:7 twist rate and is threaded 1/2x28, fitted with an A2 birdcage flash hider, and the rifle has an overall length of approximately 32.25 inches collapsed to 35.5 inches extended, with an unloaded weight of about 6.8 pounds.

  • 5.56 NATO semi-automatic rifle with Flat Dark Earth finish
