SIG SAUER M400 Sentry 5.56 NATO 16" Semi-Auto Rifle With Romeo5 Red Dot

The SIG SAUER M400 Sentry is a semi-automatic AR-15 platform rifle chambered in 5.56x45mm NATO and sold as a ready-to-run bundle. It ships with a ROMEO5 red dot, a FOXTROT-MSR full-size light and a vertical foregrip already installed, intended for home defense, training and recreational shooting.

The rifle has a 16-inch barrel with a threaded muzzle, an alloy steel construction with black anodized finish, and an ambidextrous hand configuration. It weighs about 8 pounds and accepts 30-round magazines. The receiver is optics ready and the package includes no iron sights, so the included red dot serves as the primary aiming solution.

The M400 Sentry is compatible with the AR-15 platform and also lists 223 Remington as a supported caliber. Sold as a bundle, it is offered as a complete setup without additional accessories required to begin shooting.
