SIG Sauer M400 Tread V2 5.56 NATO 16" Rifle 30rd - Moss Green

The SIG Sauer M400 Tread V2 delivers proven AR-15 reliability with enhanced ergonomics and finish durability. This 5.56 NATO chambered rifle features a 16-inch barrel and distinctive moss green Cerakote finish that resists corrosion and wear better than standard phosphate coatings.

What Makes This Different

The M400 Tread V2 incorporates SIG's direct impingement system with a mid-length gas system for smoother cycling and reduced recoil compared to carbine-length alternatives. The moss green Cerakote finish provides superior corrosion resistance rated at 2,400+ hours in salt spray testing. SIG's enhanced trigger guard and ambidextrous controls accommodate shooters regardless of dominant hand preference.

Key Features

• 16-inch 4150 chrome-moly vanadium steel barrel with 1:7 twist rate
• Moss green Cerakote finish on upper and lower receivers
• Mid-length gas system reduces felt recoil and improves reliability
• M-LOK compatible handguard with integrated QD sling attachment points
• SIG Romeo5 red dot optic ready with co-witness iron sights

Field testing demonstrates consistent 2-3 MOA accuracy with quality ammunition at 100 yards. The mid-length gas system cycles reliably with both 55-grain and 77-grain projectiles across temperature ranges from -20°F to 140°F. Law enforcement agencies have adopted the M400 platform for patrol rifle applications due to its balance of accuracy, reliability, and modularity.
