The M400 SDI X‑Series pairs a 16‑inch chrome‑moly barrel (1:7 twist, threaded 1/2x28 with a hybrid compensator/flash hider) with SIG's 2‑Stage Matchlite Duo trigger, breaking crisp at 4.5‑6.5 pounds with a flat‑blade profile for genuinely precise trigger control. A 7075‑T6 aluminum receiver, free‑floating M‑LOK handguard, and Magpul SL‑K telescoping stock back a rifle built around real ergonomics, and fully ambidextrous controls -- bolt catch/release, selector, charging handle, and mag release -- mean it runs the same whether you're left- or right‑handed. SIG's own AR‑15 platform, built to the standard the company applies to its duty and military rifles.
