Shop Springfield SAINT 300 Blackout Semi-Automatic Pistol with 9-Inch Barrel and buy guns for sale online from our gun store. With the success of Springfield Armory’s SAINT™ AR-15 Pistol in 5.56, more people than ever are requesting variations to the original version. The newest iteration in .300 BLK harnesses the power of this combat-proven round for increased capability and versatility in a compact platform.

The SAINT AR-15 Pistol features a rugged SB Tactical SBX-K forearm brace to reduce size, stabilize recoil, and enhance accuracy in one or two-hand shooting. A 9-inch CMV barrel with a 1:7 twist and A2 flash hider makes the SAINT Pistol small, fast, and ideal for CQB. The barrel is Melonite® treated inside and out to be as durable and more accurate than chrome lining.

Built with high-end features throughout, Springfield Armory’s exclusive Accu-Tite™ tension system increases the tension between the upper and the lower receivers, ensuring an ideal fit and reducing movement. The upper and lower receivers are forged Type III hard-coat anodized 7075 T6 aluminum.

The slender, M-Lok compatible handguard features Springfield Armory’s exclusive, patent-pending, rock-solid proprietary attachment system, with four attachment points anchoring it to the barrel nut. Under the handguard is Springfield’s pinned multi/mode adjustable gas block that will reliably cycle supersonic and subsonic ammo, suppressed or unsuppressed. The crisp, enhanced nickel boron coated GI single-stage trigger is paired with a Bravo Company trigger guard. The smooth-operating heavy tungsten buffer system, GI style charging handle, and Bravo Company Mod 3 pistol grip are all well-proven in previous SAINT rifle models.

To ensure durability, the M16 BCG’s bolt is precision-machined from Carpenter 158 steel, shot peened, magnetic particle inspected and finished in super-hard Melonite®. This combat-grade SAINT AR-15 Pistol carries a Magpul Gen M3, 30-round magazine.

The compact design is the perfect complement to the .300 BLK round making the SAINT AR-15 Pistol an ideal choice for home defense. At just 27.75 inches long, and weighing only 5.9 pounds, this new AR pistol in .300 BLK from Springfield Armory® delivers a lot of power in a small, fast-handling package.
