Frequently Asked Questions
Can the DB15BG fire both .223 Remington and 5.56 NATO ammunition?
Yes. The DB15BG is chambered in 5.56 NATO, which means it can safely fire both 5.56 NATO and .223 Remington cartridges. The 5.56 NATO chamber has a slightly longer leade (throat) than a dedicated .223 Rem chamber, making it the more versatile option for shooters who use both ammunition types.
Does this rifle come with sights, and what optics will fit the V-rail handguard?
The DB15BG ships without iron sights, so you'll want to add a red dot, holographic sight, or low-power variable optic (LPVO) to the Picatinny rail on the upper receiver. The V-rail handguard features rail sections at the 3, 6, and 9 o'clock positions, allowing you to mount lights, foregrips, lasers, or a front sight post to suit your setup.
This listing shows 10+1 capacity — can I use standard 30-round magazines?
The 10+1 capacity listed reflects California's magazine capacity restrictions, which limit detachable magazines to 10 rounds for rifles sold in the state. The rifle itself is mechanically compatible with standard AR-15 magazines, including the included Magpul PMAG, but California law requires that only compliant 10-round magazines be used within the state. Always follow your local laws regarding magazine capacity.
