300 Blackout AR-15 Pistols For Sale

The .300 Blackout, also known as .300 AAC Blackout or 7.62x35mm, was originally developed for special operations use in short barrel AR-platform firearms, delivering better performance than 5.56 NATO in pistol and carbine length gas system configurations. Today it has become one of the most popular AR pistol calibers available, and Sportsman's Outdoor Superstore carries a wide selection of 300 Blackout builds for home defense, hunting, and range shooting.

Explore .300 Blackout Rifles, Pistols, and More

The .300 Blackout cartridge was developed in 2010 to address performance gaps that 5.56 NATO and 9mm could not fill in special operations applications. It offered better subsonic ammunition performance than 9mm and superior results in short barrel firearms with a suppressor compared to 5.56 NATO.

Most 300 Blackout pistol builds feature an adjustable gas block and pistol length gas system. This allows shooters to tune the gas port for reliable cycling with both subsonic loads and supersonic rounds, giving the platform a level of versatility that few other calibers can match.

While .300 Blackout was quickly adopted by militaries worldwide, it has become equally popular in civilian circles. Find AR-15 Rifles and AR-15 Pistols chambered in this high-performance caliber at Sportsman's Outdoor Superstore.
