Diamondback Firearms Db15 300blk 16" 10-Round Rifle

The Diamondback Firearms DB15 300 Blackout 16-inch M-LOK rifle is a semi-automatic AR platform weapon optimized for subsonic performance and magazine-restricted jurisdictions. This New York-compliant configuration pairs the proven DB15 receiver set with a 16-inch barrel in .300 Blackout—a cartridge engineered for suppressed fire—and ships with a Thordsen Gen II FRS-15 featureless stock that meets state compliance requirements while maintaining ergonomic function.

The 16-inch barrel length in .300 Blackout delivers optimal velocity from subsonic ammunition—critical for suppressed operations—while keeping overall rifle length manageable for vehicle storage and close-quarters handling. M-LOK slots integrated along the handguard provide attachment points for tactical accessories without rail clutter. The 10-round magazine capacity reflects New York's statutory limit. Diamondback Firearms maintains tight tolerances on receiver fitment, and the featureless stock design maintains consistent trigger control geometry compared to pinned fin variations found in other compliant models.

This rifle targets shooters in restricted states who prioritize .300 Blackout's subsonic ballistics for suppressed duty use, training, or hunting applications where compliance and suppressor-ready barrel geometry are non-negotiable. LEOs and operators in NY and similar jurisdictions requiring featureless configurations will find the Thordsen stock's ergonomic profile superior to traditional fin grips. The 10-round magazine constraint is standard for NY sales; shooters should verify local regulations before purchase.

Diamondback Firearms DB15 rifles are known for reliable semi-automatic function and consistent accuracy in the AR platform class. The .300 Blackout chambering has proven effective for suppressed shooting across law enforcement and civilian markets. Magazine-limited builds have become standard in compliant states, and this DB1796B001 configuration combines factory precision with regulatory necessity—a practical solution where legal constraints and operational capability must coexist.
