Short-barreled semi-auto rifles have become a go-to option for shooters who need compact handling without sacrificing terminal performance. A careful build that balances barrel length, gas system, and reliable components can deliver accuracy and controllability out of a 10″ platform.

DIAMONDBACK DB15 is built around a 10″ Chrome Moly Vanadium barrel with a heavy threaded profile and A2 flash hider, chambered in .300 AAC Blackout and packaged as a 30+1 system with a Magpul Gen3 PMAG included. The rifle pairs flat dark earth Cerakote aluminum receivers with a 9″ M-LOK handguard, an SB Tactical SBA3 brace, and a Magpul MOE grip to deliver a tactically capable, user-friendly package.

Key features and what they mean on the range

The 10″ Chrome Moly Vanadium barrel gives the platform durability and good resistance to wear for fast follow-up shots. A pistol-length direct impingement gas system is tuned for short barrels, reducing the bolt carrier group’s cyclic rate and improving controllability when running supersonic or subsonic .300 AAC Blackout loads. The shot-peened, magnetic particle inspected Mil-Spec 8620 carrier adds longevity and reliability to the action.

Chassis, controls, and ergonomics

Flat Dark Earth Cerakote aluminum receivers and the 9″ M-LOK handguard keep weight manageable while offering accessory mounting options. The SB Tactical SBA3 brace provides a stable cheek weld and compact shooting profile without adding excess length. A Magpul MOE grip improves handling and natural trigger control for defensive or precision work.

Magazine and capacity

The package includes a 30rd Magpul Gen3 PMAG, delivering high-capacity reliability for training, range days, or duty use. At a listed price of $776.99, this setup offers competitive value for a complete short-barrel .300 AAC Blackout system in the Semi Auto category.

Performance, ammunition, and practical uses

.300 AAC Blackout excels from short barrels: it retains energy better than some rifle calibers at suppressed velocities and cycles well with both supersonic and subsonic loads. That versatility makes the DIAMONDBACK DB15 suited for close-quarters work, suppressor-equipped training, or hunting smaller game where compact handling is an asset. Expect a balance of muzzle energy and controllability, especially with the platform’s pistol-length gas system and heavy threaded barrel.
