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.
