Overview & Features

The Springfield Saint 5.56mm semi-automatic AR-15 rifle with M-Lok rail is built around a 16-inch, chrome-moly vanadium steel barrel with a 1:8 twist rate, optimized to stabilize a wide range of bullet weights from 55-grain to 77-grain match loads. The free-float M-Lok handguard provides ample real estate for lights, lasers, and foregrips while keeping your support hand cool during extended strings of fire. The forged 7075 T6 aluminum upper and lower receivers are hard-coat anodized for corrosion resistance and dimensional stability. Inside, the single-stage trigger breaks cleanly at approximately 4.5 to 5 pounds, giving you a crisp pull that aids accuracy without being too light for defensive use. The rifle ships with a six-position collapsible buttstock and a mil-spec carbine buffer system, ensuring a proper fit for shooters of all sizes.
