300 Blackout Used Guns For Sale

.300 Blackout (also known as .300 AAC Blackout or 7.62x35mm) was initially designed for the M4 carbine for use in special operations, but it's become a common caliber for all AR-platform firearms to be chambered in. .300 Blackout rifles and pistols provide better performance than 5.56 NATO in guns with shorter barrels and silencers. Whether you're looking for a firearm for home defense, hunting, or just something to show off at the range, you can find it in the collection at Sportsman's Outdoor Superstore.

Special ops missions require the best of the best equipment. Neither 5.56 NATO nor 9mm Parabellum provided the performance these sensitive missions needed, which meant a new one needed to be made.

In 2010, production of both .300 Blackout cartridges and firearms began. These rounds provided better subsonic performance than 9mm and better performance in short-barreled firearms with silencers than 5.56 NATO.

While .300 Blackout rifles, pistols, and carbines were quickly adopted by militaries worldwide, they also became incredibly popular in civilian circles. You can find AR-15 rifles and AR-15 pistols chambered in this high-performance caliber. Find the .300 Blackout gun that's right for you at Sportsman's Outdoor Superstore.

Frequently Asked Questions

What are .300 Blackout guns good for?

.300 Blackout was made for combat, so it's a fantastic caliber for self-defense weapons. It's especially effective in SBRs and rifle-caliber handguns. However, its size and kinetic energy make it a good caliber for hunting medium-sized game, too.

Does a .300 Blackout cartridge kick hard?

.300 Blackout has much higher recoil than 5.56 NATO, with tests showing it has around 30% more recoil. However, it's intended for SBRs and carbines, weapons of choice for close-quarters combat where recoil doesn't have as detrimental of an effect. The increased recoil is worth the performance improvements.

Can you deliver .300 Blackout rifles or pistols to my home?

We cannot send any firearms to residential addresses. Instead, we can send it to your local FFL dealer. You can pick up your order from them after it arrives.
