Frequently Asked Questions
Can the DB15 fire both 5.56 NATO and .223 Remington ammunition?
Yes. The DB15 is chambered in 5.56 NATO, which means it safely accepts both 5.56 NATO and the slightly lower-pressure .223 Remington cartridges. This gives you flexibility at the range and when sourcing ammunition.
What accessories can I mount on the quad rail handguard?
The Picatinny-style quad rail system provides four full-length rail sections (top, bottom, left, and right), allowing you to mount a wide variety of accessories including tactical lights, laser sights, vertical foregrips, bipods, and more — all without adapters.
Is the DB15 sold with a 10-round magazine for California compliance?
Yes. As listed, this DB15 comes configured with a 10+1 capacity to meet California's magazine capacity regulations. California law prohibits the sale of centerfire semi-automatic rifles with detachable magazines holding more than 10 rounds, and this rifle is sold accordingly at Goodland Guns.
