Description: Sig Sauer M400 SDI XSERIES Rifle, 5.56mm 16" Barrel. Designed with additional features over the original M400 Tread, this XSERIES SDI M400 from Sig Sauer boasts a 16" barrel, a black anodized finish, a lightning cut upper/lower and is chambered for 5.56x45mm. The barrel is cut with 1/2" x 28 TPI threads with a hybrid compensator / flash hider installed. The M-LOK handguard features a clamping system for lower deflection and the SDI M400 offers an ambidextrous mag catch, bolt release, safety and charging handle. A SIG flat blade match trigger is installed as well as a Magpul SL 6 position stock. The M400 SDI X-SERIES is built to be a sharply upgraded rifle right out of the box; no need to worry about those small post-purchase upgrade projects. As with all Sig rifles, this model is built to perform and is ideal to customize to your comfort, shooting and situational needs.

The SIG SAUER M400-SDI XSERIES packs a rich set of features and upgrades into the M400 platform delivering an advanced performance rifle right out of the box. The M400 XSERIES lower features fully ambidextrous controls, including bolt catch & release, selector switch, charging handle and mag release. Also unique to the XSERISE is a precision machined lightning cut upper and lower with a handguard clamp system designed to minimize deflection when using mounted accessories. Other features include a hybrid flash hider/compensator, 2-Stage Matchlite Trigger and Magpul SL Telescoping Stock.

I owned my SDI now for about a year now. Put at least 3000 rounds threw it.No jams or miss fires. It seems to be a solid well made rifle. Has some great upgradeā€™s right from the factory for being under a $2000.00 rifle.
