Short-barreled rifles are increasingly popular for home defense and close-quarters work because they balance maneuverability with serious terminal performance. Built to be light, rugged, and ready for accessories, this rifle is geared toward operators and responsible owners who want a compact platform without giving up reliability.

DIAMONDBACK DB15

Why this platform matters

The DIAMONDBACK DB15 presents a focused spec sheet: a 10″ barrel chambered in 300 Blackout, pistol-length gas system, and a 28+1 capacity magazine. At 23″ overall and 5.1 lbs, it’s designed for quick presentation and minimal fatigue. The 1:8″ barrel twist supports a wide range of 300 Blackout loads — from heavier subsonic rounds to supersonic options — making it versatile across defensive and training roles.

Key features examined

Build and durability

Both upper and lower receivers are forged 7075 T-6 aluminum, with the lower featuring Diamondback Carbon for reduced weight without sacrificing strength. The bolt carrier group is shot-peened and magnetic particle inspected with a Mil-Spec 8620 carrier — a detail that signals a focus on longevity under duty use.

Ergonomics and accessory readiness

The 9″ M-LOK handguard gives ample real estate for lights and grips while keeping mass forward. The padded buffer tube with foam pad and Moe Grip provide comfortable handling. The A2 flash hider (5/8 x 24) and standard trigger mean this rifle is optic-ready out of the box, as sights are not included.

Performance and applications

300 Blackout shines out of short barrels: subsonic suppressed loads reduce signature for tactical scenarios, while supersonic rounds offer effective short-range stopping power. The pistol-length gas system paired with a 10″ barrel tends to soften recoil impulse and improves reliability with heavier projectiles.

With a 28-round CPD magazine and a total package price of $726.99, the DIAMONDBACK DB15 represents a competitive value for a mission-focused semi-auto.

Making the decision

If you want a compact, purpose-built package with a proven chambering for short-barrel performance and a strong component set — forged 7075 receivers, inspected BCG, 9″ M-LOK, and a padded buffer tube — this rifle deserves consideration.
