The modern AR-style rifle continues to evolve for shooters who want a balance of durability, modularity and practical performance for range use, home defense or duty carry. The DIAMONDBACK DB15 CARBON SERIES brings functional upgrades and a dual-caliber option that makes it a versatile choice for any semi-auto platform enthusiast.
DIAMONDBACK DB15 CARBON SERIES
Platform and ergonomics that matter
This Semi Auto DIAMONDBACK unit pairs a modern flattop design with a mil-spec style lower receiver for the classic M4 silhouette. Practical touches include MagPul MOE furniture — both the stock and the pistol grip — which deliver improved ergonomics over standard M4 components. The rubber buttpad on the stock reduces felt recoil during rapid strings of fire, helping keep follow-up shots controlled.

Barrel, finish and dual-caliber capability
The medium profile barrel on the DB15 Carbon strikes a balance between weight and heat management, offering repeatable accuracy without excessive bulk. This model features an FDE Cerakote finish that resists wear and provides a subdued tactical appearance. Notably, the package includes an additional upper chambered in .300 AAC Blackout, expanding the rifle’s mission set for suppressed or subsonic use.
.300 AAC Blackout: practical advantages
.300 AAC Blackout is well-suited for suppressed builds and short-barrel platforms, offering improved terminal performance over intermediate calibers when optimized with subsonic loads. For shooters who value a multi-role rifle, having a second upper in .300 AAC Blackout increases flexibility for close-quarters training and reduced-noise operations.
What’s included and pricing
The DIAMONDBACK DB15 CARBON SERIES ships with one MagPul M2 30-round magazine and the additional .300 AAC Blackout upper. Priced at $940.99, it presents a competitive dual-caliber package for those seeking value in a Semi Auto platform. This combination of MOE MagPul ergonomics, medium profile barrel and FDE Cerakote makes it a practical choice for shooters upgrading from basic M4-style rifles.
