Sig Sauer M400 SDI XSeries 5.56 AR-15 Rifle - 16" - Flat Dark Earth - 1x 30rd Mag

The SIG Sauer M400 SDI X was developed with input from SIG Sauer Academy instructors, giving shooters fully ambidextrous controls including a bolt catch and release unique to the M400-SDI lower receiver. Built for both left- and right-handed shooters, this AR-15 rifle makes transitional shooting easier while delivering advanced performance out of the box.

Features:

• Low-profile gas block with mid-length gas system
• Compensator/flash hider
• Free float handguard with dual clamp steel lockup system
• Accessory mounting on all four sides with no effect on accuracy
• Ambidextrous bolt catch and release
• SIG 2-Stage Matchlite Duo trigger, 4.5-6.5 lb pull, flat blade design
• Magpul SL stock
• Includes one magazine

The dual clamp steel lockup design significantly reduces handguard deflection compared to a standard clamp system, providing maximum rigidity so accessories mounted on any of the four sides don't affect accuracy. The ambidextrous bolt catch and release, unique to the M400-SDI lower receiver, gives left- and right-handed shooters identical control access for faster transitions. The SIG 2-Stage Matchlite Duo trigger breaks crisp at 4.5 to 6.5 pounds with a flat blade design for a precision feel straight out of the box. This rifle is finished in Moss Green Cerakote for added durability.

SIG Sauer built the M400-SDI X in collaboration with instructors from the SIG Sauer Academy, applying decades of professional shooting instruction experience to the rifle's design.
