The Springfield Saint AR pistol in 5.56 was introduced back in November, but it was only a matter of time before the company added a .300 BLK option. That day has arrived.

The Springfield Saint AR pistol in .300 BLK comes with a SB Tactical SBX-K brace; nine-inch CMV, melonite-treated barrel with a 1:7 twist and A2 flash hider; forged Type III hardcoat anodized 7075 T6 aluminum upper and lower receivers; M-LOK compatible handguard; pinned multi/mode adjustable gas block; enhanced nickel boron coated GI single-stage trigger; Bravo Company trigger guard; GI style charging handle; Bravo Company Mod 3 pistol grip; and heavy tungsten buffer system.

This model also features a M16 bolt carrier group which is precision-machined from carpenter 158 steel, shot peened, magnetic particle inspected and finished in melonite. In addition, it’s fed from a 30-round Magpul Gen M3 magazine.

Weighing just 5.9 pounds and measuring 27.75 inches in overall length, Springfield says the .300 BLK Saint is a solid choice for home defense. MSRP: 989. Specs are below, along with a video.
