Diamondback 300 Blackout AR-15 Pistols

The Diamondback DB15 is Diamondback's tactical AR-15 pistol, designed to provide the best performance possible in a compact form factor. Because no two shooters' needs are the same, they're offered in different configurations with a variety of attachments, features, and calibers. Explore the collection of Diamondback DB15s in 5.56 NATO, .308 Winchester, and more at Sportsman's Outdoor Superstore.

.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.

Frequently Asked Questions

Can a 5.56 Diamondback DB15 shoot .223 Remington?

Yes, Diamondback's pistols chambered for 5.56 NATO can shoot .223 Remington. However, we recommend using the official ammunition the gun is chambered for. Using 5.56 rounds may cause issues with velocity and accuracy.

What is a Diamondback AR-15 pistol good for?

Diamondback's DB15 line of pistols were designed for a few use cases: hunting, self-protection, and recreation. Built on the AR-15 platform, you can easily find several configurations that are suited for close-range whitetail hunting. As a much more compact alternative to AR-15 rifles, they're perfect as a home defense weapon, where claustrophobic hallways and tight corners are your biggest obstacle. And if you ever have a chance to use one at the range, you'll quickly see just how fun they are to shoot.

Can you deliver a 5.56 Diamondback DB15 to my home?

Regardless of caliber, your Diamondback DB15 must be sent to your local FFL dealer. Firearms can only be shipped to someone with an FFL, which prevents us from delivering your order directly to you. After your package arrives at the gun store of your choice, you can pick it up from them.
