Diamondback DB15 5.56x45mm NATO 16" 30+1 Semi-Auto Rifle

The Diamondback DB15 is a semi-automatic AR-15 platform rifle chambered in 5.56x45mm NATO and ready to run out of the box. A 16" medium-profile 4150 chrome moly barrel carries a 1:8" twist that stabilizes a wide range of bullet weights from light varmint loads up through heavier match projectiles. The action runs on a mid-length gas system with a shot-peened Mil-Spec 8620 bolt carrier, balancing reliable cycling with soft recoil for both range and duty use.

Up front, the rifle wears a 15" M-Lok anti-rotation handguard for accessory mounting and an Obsidian muzzle brake at the crown. The lower receiver is machined from aluminum with a black finish, paired with a Magpul CTR adjustable carbine stock and a Magpul K2 pistol grip. Controls include an ambidextrous safety for left- and right-handed manipulation. The rifle ships with a detachable 30-round magazine for a total 30+1 capacity. No iron sights are installed, leaving the top Picatinny rail clean for an optic of the shooter's choice.

Overall length adjusts from 33" to 36.25" via the collapsible CTR stock, and the complete rifle weighs 6.60 lbs. The DB15 is configured for right-handed shooters and ships as a complete, ready-to-fire centerfire rifle.
