Overview

Springfield Armory developed the Saint series to provide shooters with a ready-to-run AR-platform pistol that requires no aftermarket modifications for dependable use. The Springfield Saint 5.56mm AR15 pistol with 9.6 inch barrel, M-Lok rail and blade stock combines a lightweight profile with the ballistic performance of 5.56mm NATO ammunition. The 9.6-inch barrel balances velocity retention with maneuverability, while the M-Lok free-float handguard offers extensive accessory mounting options. The SB Tactical blade-style stabilizing brace allows for improved one-handed or braced shooting without adding unnecessary bulk.

Features & Specs

This pistol is built around a forged 7075 T6 aluminum upper and lower receiver set with a hard-coat anodized finish. The 9.6-inch barrel features a 1:8 twist rate, optimized for stabilizing both 55-grain and 62-grain projectiles. The M-Lok rail system provides continuous attachment points for lights, lasers, or vertical grips without interfering with barrel harmonics. The single-stage nickel-boron coated trigger delivers a crisp break with minimal overtravel.
