Sig Sauer M400 5.56 Nato 16 inch 30 round Blued and Black Magpul SL K

The SIG RM40016BTRDV2 M400 556 V2 is part of Sig Sauer's M400 TREAD series, a semi-auto 5.56 NATO rifle built for duty, range days, and serious hunting when a lightweight, hard-hitting AR-platform is needed. The rifle pairs a 16" stainless steel, threaded barrel with a 1:8 twist and 3-prong flash hider to resist corrosion, cycle a wide range of bullets, and maintain consistent accuracy; its mid-length gas system smooths recoil impulse for faster follow-up shots and more comfortable shooting over long sessions. A free-floating M-LOK enhanced handguard keeps weight down while providing rigid mounting real estate for lights, optics, and handstops, and the aluminum lower with ambidextrous safety and integrated QD sling mount supports both right- and left-handed shooters and practical sling use in the field or on patrol. The SIG Matchlite two-stage trigger offers a crisp, predictable break for precise shot placement, and the Magpul SL-K telescoping stock provides quick length-of-pull adjustment for different gear or shooting positions. With a 30+1 capacity, 6.50 lb weight, 32.5" overall length, and durable black finish, this rifle suits training, competition, and tactical or hunting applications while requiring standard FFL transfer.
