The Diamondback Firearms DB-15 Modern Sporting Pistol is engineered to deliver exceptional performance, reliability and customization in a compact AR-style platform. Chambered in 5.56mm NATO with a 10-inch black nitride-coated 4150 chrome moly barrel, this pistol brings the power and versatility of a carbine into a highly maneuverable package. Whether you are a competitive shooter, tactical professional or home defense enthusiast, the DB-15 pistol offers the perfect balance of durability, accuracy and ergonomic comfort.

Premium Barrel and Gas System
The heart of the DB-15 pistol is its 10-inch medium-profile barrel crafted from 4150 chrome moly, then treated with a corrosion-resistant black nitride finish. This barrel length optimizes velocity and maneuverability, making it ideal for both close-quarters engagements and precision shooting at extended ranges. The pistol-length gas system ensures reliable cycling and reduced recoil impulse, while the threaded muzzle allows for the installation of a flash hider, muzzle brake or suppressor to suit your shooting needs.

Mil-Spec Bolt Carrier Group
Inside the upper receiver resides a shot-peened, Mil-Spec 8620 bolt carrier group (BCG) for consistent performance and ease of maintenance. The phosphate-coated bolt and carrier surfaces provide smooth cycling and enhanced wear resistance. Each component undergoes rigorous testing to ensure proper headspace and flawless operation, contributing to the overall reliability of the DB-15 pistol under heavy use and adverse conditions.

Lightweight, Durable Receivers
The DB-15 Modern Sporting Pistol features forged 7075-T6 aluminum upper and lower receivers, providing an excellent strength-to-weight ratio. Precision-machined to Mil-Spec tolerances, the receivers ensure a rock-solid fit with minimal play between components. The contrasting black nitride finish on the lower receiver complements the handguard and barrel coating for a sleek, tactical appearance.

Ergonomic Controls and Customization
Diamondback Firearms equipped the DB-15 pistol with an ambidextrous safety selector, an oversize charging handle, and a Magpul MOE grip for improved ergonomics and ease of use. The 9-inch free-floating M-LOK handguard offers multiple attachment points for lights, lasers, grips and other accessories without adding unnecessary weight. A foam-padded buffer tube pad enhances shoulder comfort and helps reduce muzzle rise during rapid fire.

Optic-Ready and Sight Options
The upper receiver is machined with a Picatinny rail, making it simple to mount red dot sights, scopes or other optical devices. Iron sights can be co-witnessed with many optics on the rail, or removed entirely if you prefer a minimalist setup. The optic-ready configuration allows you to tailor the DB-15 pistol to your tactical or competition requirements with ease.

High-Capacity Magazine and Performance
The DB-15 pistol ships with a 30-round polymer magazine, offering ample capacity for range sessions, tactical drills or personal defense scenarios. The magazine release and bolt catch are strategically placed for quick magazine changes and speed reloads. Chambered in the widely available 5.56mm NATO cartridge, the DB-15 delivers controllable recoil, consistent ballistics and compatibility with a vast selection of ammunition types.

Applications and Versatility
From home defense to tactical training, the Diamondback DB-15 pistol excels in diverse roles. Its compact footprint and lightweight design make it maneuverable in tight spaces, while the 10-inch barrel ensures sufficient muzzle velocity and accuracy for mid-range engagements.
