What's in the Box

  • Saint 5.56mm Semi-Automatic Rifle with M-LOK
  • (1) 30-Round Magazine
  • Springfield Soft Rifle Case
  • Cable Lock
  • Owner's Manual

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. 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.

Unlike many AR-15s on the market, the SAINT family of rifles feature an upgraded trigger right out of the box. The nickel boron-coated GI single-stage trigger operates smoothly and provides a clean, grit-free pull. These M-LOK compatible SAINTs also use a mid-length gas system with an “H” heavy tungsten buffer, designed to mitigate snappy recoil and ensure a smooth, accurate, and comfortable shooting experience. The Accu-Tite™ tension system provides a tight, wobble-free fit between the upper and lower receivers, which are constructed from Type III hard anodized aircraft-grade 7075 T6 aluminum.

Bravo Company outfits the M-LOK compatible SAINT rifles with quality furniture, including the upgraded BCM Gunfighter stock, the Mod 3 pistol grip, and the BCM trigger guard. One 30-round Magpul PMAG is included.
