Description
SIG Sauer M400 TREAD V2 Rifle, 5.56 NATO, 16-Inch Barrel, Moss Green, 30-Round
The SIG M400 TREAD V2 moss green is SIG’s no-compromise AR in moss green Cerakote: a 16 in. stainless barrel, mid-length gas, Matchlite Duo, and a TREAD-engraved free-float M-LOK handguard.
TREAD V2 is SIG’s no-compromise AR. A 16 in. stainless barrel, mid-length gas, and a Matchlite Duo two-stage sit under a TREAD-engraved free-float M-LOK handguard. SIG built V2 from shooter feedback: more handguard, a cleaner trigger, Magpul’s SL-K stock. The lower is ambidextrous on the safety and magazine release, with QD cups on the receiver.
The stainless barrel is 1:8 twist with SIG’s 3-prong flash hider on a 1/2-28 tapered shoulder. Mid-length gas is the V2 default. Magpul’s SL-K stock is six-position. The rifle is 6.5 lb, 35.8 in. extended and 32.5 in. collapsed. Width is 2.6 in. Height is 7.1 in.
This moss green TREAD V2
Moss green Cerakote is the finish. The stainless 16 in. barrel, 3-prong flash hider, Matchlite Duo, and Magpul SL-K match the black TREAD V2. One 30-round magazine ships in the box. A factory red dot is not installed.
