Springfield Armory

Introducing new M-LOK compatible SAINT rifles chambered in 5.56mm NATO. These SAINT rifles now feature slim M-LOK compatible handguards from Bravo Company, with an internal aluminum heat shield.

The SAINT rifles now come in two configurations – one model features a pinned, picatinny railed gas block and includes an SA low-profile flip-up front sight, and the other has an A2-style front sight and pinned gas block. Each M-LOK compatible SAINT model includes a low-profile, dual aperture flip-up rear sight with ½ minute of angle windage adjustments.

At the heart of these SAINT rifles is an M16 bolt carrier group, with a Carpenter 158 steel bolt that has been shot-peened and magnetic particle tested to meet the most demanding durability requirements. The 16-inch barrel is made of Chrome Moly Vanadium and Melonite® coated inside and out for longevity and corrosion resistance. A 1:8-inch twist rate barrel is capable of stabilizing a broad range of ammunition types and projectile lengths. The rifles are a lightweight 6.11 ounces, capable of quick and easy handling under strenuous conditions.
