Features & Specs
Springfield Armory did not cut corners on the Saint. Every component is selected for durability and accuracy, making this one of the most dependable 5.56mm semi-automatic AR-15 rifles on the market. The M-LOK rail system is free-floated, which means your barrel stays consistent shot after shot. Here is a breakdown of what you get with the Springfield Saint 5.56mm semi-automatic AR-15 rifle with M-LOK rail:
- Barrel: 16-inch chrome-moly vanadium steel with Melonite finish, 1:8 twist rate, and a carbine-length gas system. The muzzle is threaded 1/2×28 for standard flash hiders or suppressors.
- Handguard: 15-inch free-float M-LOK rail with a full-length Picatinny top rail for optics and backup sights. The slim profile makes it easy to get a solid C-clamp grip.
- Receiver & Bolt: Forged 7075 T6 aluminum upper and lower receivers with a hard-coat anodized finish. The bolt carrier group is shot-peened and MPI tested, with a nickel boron coated carrier for smooth cycling.
Other notable specs include a standard mil-spec buffer tube, a polished trigger with a crisp break, and an adjustable stock. The rifle ships with one 30-round Magpul PMAG and a padded soft case.
