Features & Specs

The Springfield Saint 5.56mm semi-automatic AR-15 rifle with M-LOK rail is built around a 16-inch, chrome-moly vanadium barrel with a 1:8 twist rate, optimized for both 55-grain and 62-grain ammunition.

Who It’s For

This rifle suits the civilian shooter who needs a capable home-defense carbine, the competitive shooter who wants a reliable 3-gun platform, and the hunter who requires a lightweight .223/5.56 rifle for varmints or predators. The M-LOK rail allows you to attach lights, lasers, vertical grips, or bipods without adding bulk. The Springfield Saint 5.56mm semi-automatic AR-15 rifle with M-LOK rail is also an excellent choice for the first-time AR buyer who wants a turnkey firearm that does not require immediate upgrades. Experienced shooters will appreciate the chrome-lined gas key and the nitride-treated barrel that extends service life. If you need a rifle that runs out of the box with standard 5.56 or .223 Remington ammunition, this model delivers consistent function without compromise.
