Frequently Asked Questions

What makes the DB10 different from a standard AR-15 build?

The Diamondback DB10 is built on the AR-10 platform, which is scaled up to accommodate the larger .308 Winchester cartridge. Compared to an AR-15, the DB10 delivers significantly more energy and effective range, making it better suited for big-game hunting and long-distance shooting. The forged 7075 T-6 aluminum receiver and Carakote finish also give it a durability advantage over many entry-level builds.

Is the Magpul P-Mag included, and are other magazines compatible?

Yes, the DB10 ships with one Magpul P-Mag 20-round magazine ready to go. It is generally compatible with SR-25/DPMS-pattern .308 magazines, which are widely available from brands like Magpul, Lancer, and others. Always confirm magazine compatibility with your specific lower receiver pattern before purchasing additional magazines.

Can this rifle be sold in California, and does it require any modifications?

California has specific regulations regarding semi-automatic centerfire rifles, including restrictions on features such as folding/collapsible stocks and magazine capacity. Because the DB10 Duo includes a folding/collapsible stock and ships with a 20-round magazine, it may require California-compliant modifications — such as a fixed-stock conversion or a featureless configuration — before it can be legally transferred in the state. Goodland Guns can advise you on compliant options at the time of purchase.
