Diamondback

Overview

The Diamondback 223WR18H50B7 is an 18" barrel designed specifically for .223 Wylde, allowing for reliable chambering of both .223 Remington and 5.56 NATO cartridges. This barrel length offers a balance of velocity and maneuverability, making it suitable for a variety of shooting applications. Builders often incorporate this barrel into mid-length gas system setups, which enhances reliability while providing a softer recoil impulse.
