Diamondback Firearms DB15PC 300BLK Pst 10B 30RD

Product Description

The Diamondback Firearms DB15PC is a semi-auto AR-style pistol chambered in .300 Blk, built around a 10″ 4150 chrome moly barrel. It holds 30+1 rounds and comes with one metal AR-style magazine. Overall length is 26″.

The receiver is forged 7075 T6 aluminum with a black anodized hard coat finish. The action is direct impingement with a pistol-length gas system. A manual safety and a standard trigger handle the controls. Up front, the barrel is threaded and wears an A2 flash hider, so the muzzle device can be changed.

Rail, optic mount and grip

A 9″ M-LOK rail covers the front end. M-LOK slots take lights, grips and other accessories without adding bulk. The pistol has no sights, but the integral Picatinny mount sits at 0 MOA and is ready for a red dot or other optic. A MOE grip and a buffer tube with a foam pad finish out the rear.

This pistol suits shooters who want .300 Blk in a short, handy format. It works for range days, truck-gun duty and building a custom setup. Good pairings include a red dot or compact magnified optic, a weapon light on the M-LOK rail, a sling, and extra AR-style magazines. Because it ships without sights, plan on mounting an optic before your first range trip.
