SIG Sauer M400 TREAD V2 5.56 NATO CA Compliant Rifle, 16-Inch, 10-Round
The SIG M400 TREAD California is the 10-round CA configuration of SIG’s no-compromise TREAD V2: a 16 in. stainless barrel, mid-length gas, Matchlite Duo, and a TREAD-engraved 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.
