SIG Sauer M400 Forge 5.56 AR Pistol - 11.5" - 1x 30rd Mag

The SIG Sauer M400-FORGE Pistol brings duty-grade AR performance to a compact, brace-equipped platform. Built around an 11.5-inch cold hammer forged barrel and carbine-length gas system, this 5.56 NATO pistol is engineered for durability, smooth cycling, and reliable accuracy in a package that's easier to maneuver than a full-length rifle.

Features:

• 11.5" cold hammer forged barrel with 1:7 twist and A2 birdcage flash hider
• TriggerTech 3.5-pound two-stage flat blade duty trigger
• ROMEO-MSR Gen II 2 MOA red dot included
• Full-length free-floating M-LOK handguard and ambidextrous charging handle
• MAGPUL BSL arm brace for stability without added bulk

A cold hammer forged barrel delivers long-term durability and consistent accuracy over high round counts, paired here with a carbine-length gas system for smooth, reliable cycling. The TriggerTech 3.5-pound two-stage flat blade trigger provides a crisp, predictable break, and the included ROMEO-MSR Gen II red dot brings 12 illumination settings, a 35,000-hour runtime, and IPX7 waterproofing to fast target acquisition right out of the box.

At 6.2 pounds and 27.8 to 29.8 inches overall, the M400-FORGE Pistol strikes a compact, capable balance for professional applications, home defense, or range use, backed by a 30-round magazine standard.

SIG Sauer built its M400 line on the same architecture the company has supplied to military and law enforcement customers worldwide. The FORGE series takes that proven platform and upgrades the barrel, trigger, and optic in one factory-built package.
