Diamondback Firearms Db15 5.56 16" 30-Round Rifle

The Diamondback Firearms DB15 5.56 16" M-LOK 30-round rifle is a modern AR-pattern platform engineered for shooters who demand versatility without compromising on ergonomic customization. Built around a 16-inch barrel chambered in 5.56 NATO/.223 Remington, this semi-automatic rifle delivers the velocity and accuracy window essential for intermediate-distance precision while maintaining a compact overall profile suitable for both tactical training and duty applications.

The standout specification is the integrated 15-inch M-LOK handguard, which provides extensive rail real estate for mounting optics, lights, vertical grips, and other modular accessories without unnecessary weight. At 7.88 lbs unloaded, the DB15 balances shootable heft for recoil management with handleability during transitions and movement. The rifle ships with a 30-round magazine and a six-position stock, allowing length-of-pull adjustment across diverse shooter frames and gear configurations—critical for operators running body armor or bulky outerwear.

The DB15 serves law enforcement, military support roles, and serious recreational shooters conducting carbine courses or transitional training. The 16-inch barrel length sits in the practical sweet spot—short enough for vehicle or room-clearing scenarios, long enough to extract reliable velocity from 5.56 rounds across varied engagement distances. The 1/2-28 thread pattern on the muzzle accommodates standard suppressors, flash hiders, and muzzle devices, expanding capability for noise-sensitive training environments.

Diamondback Firearms positions the DB15 as an accessible, no-frills AR platform that doesn't sacrifice core functionality. The black finish resists corrosion under standard storage and field use. This configuration is ideal for shooters building a duty-grade rifle or upgrading to a more ergonomic platform without premium pricing on brand heritage alone.
