Description
Product Overview
The SIG Sauer M400 SDI-X is a 5.56 NATO semi-automatic rifle developed with input from SIG Sauer Academy instructors. It combines fully ambidextrous controls with a free-floating handguard that uses a dual-clamp steel locking system to reduce deflection and support consistent accuracy. The 16-inch barrel uses a mid-length gas system and low-profile gas block, while the SIG 2-Stage Matchlite Duo flat trigger provides a crisp 4.5- to 6.5-pound pull. A Magpul SL stock, threaded barrel, and accessory-ready handguard complete this versatile rifle configuration.
