New AR: Springfield’s SAINT Pistol Goes .300 Blackout

Following on the success of the 5.56 SAINT Pistol, Springfield has introduced a .300 BLK model.

The pistol's saintly virtues:

  • Springfield introduced the SAINT Pistol in the fall of 2017 in 5.56 NATO.
  • Available now in .300 BLK, the line has a versatile medium bore-option.
  • The new pistol features an SB Tactical SBX-K forearm brace.
  • It's outfitted with a 9-inch barrel, Melonite treated inside and out.
  • The SAINT Pistol measures 27.75 inches in overall length.
  • It also boasts Springfield's Accu-Tite tension system in the receiver.
  • The MSRP of the pistol is $989.

As expected in a firearm more than a half-century old, the concept of the AR-15 has evolved over the years. From the compact, versatile carbines to decked-out, long-range specialists, the rifle is a far cry from its fixed stock and triangular handguard roots. In recent years, the firearm has made its most radical break from its original design with the new generation of highly condensed, wicked effective AR pistols.


These abbreviated additions to Eugene Stoner‘s spawn have armed tactical operators and everyday citizens with overwhelming firepower, quick handling and top performance all in one sweet little package. They are the epitome of nimbleness and power. And it keeps getting better for the for the abbreviated AR platform.

Most recently, Springfield Armory has taken another step to advance the short and wicked guns with the addition of the SAINT Pistol in .300 Blackout. Coming just a few months after the release of the line's first pistol, in 5.56 NATO, the medium-bore option adds increased capabilities and versatility to the popular line. Additionally, for those who shoot suppressed, it also opens the pistol to a round designed specifically (in its sub-sonic loads) for an optimized signature coming out of a can.

As striking as the original, the new SAINT Pistol boasts many of the same features, including the SB Tactical SBX-K forearm brace. The unique stabilizer keeps the gun at a very manageable 27.75-inches in overall length while enhancing its accuracy potential whether shooting one or two-handed. Additionally, the new SAINT Pistol comes equipped with 9-inch CMV barrel (1:7 twist rate) that's Melonite treated inside and out. This, Springfield claims, is among the more notable features, giving the bore more durability than a chrome lining.


The new SAINT Pistol makes use of the company's revolutionary Accu-Tite tension system, which ensures the ideal fit and reduces movement by increasing the tension between the 7075 T6 aluminum upper and lower receivers. Furthermore, the gun's slender M-LOK compatible handguard is engineered for a fighting firearm, with four anchor points attaching it to the barrel nut, making it ready for rugged use. Not to mention, the slender design allows the utmost control of the rifle's fore, facilitating a full grip.

Rounding out the SAINT Pistol is a multi-mode adjustable gas block (ideal for tuning between sub and supersonic ammo), a nickel-boron coated GI single stage trigger, a heavy tungsten buffer system and a M16 BCG’s bolt that is precision-machined from Carpenter 158 steel, shot peened, magnetic particle inspected and finished in super-hard Melonite. The MSRP of the SAINT Pistol is right in line with the original — $989.
