➲ Barrel

The barrel is one of the few components that directly affect the accuracy and weight of your build. Designed for corrosion resistance, this barrel will not let you down. This barrel is machined from 4150 Chrome Moly Steel, heat treated to RC 28-32 hardness, and properly stress relieved. This barrel has a nitride finish for increased strength and durability. It is chambered 9mm chamber, with a 1:10 twist rate. This is the perfect barrel for an AR9 build, keeping weight to an absolute minimum, while still offering a significant ballistic advantage.

➲ Afterburner Compensator

The muzzle device is designed to perform a specific task, like suppress flash intensity or reduce felt recoil. This Afterburner compensator is machined from quality steel and finished with an exceptionally corrosion resistant salt bath nitride for a lifetime of service. It utilizes a linear design to direct the high-pressure gas behind the bullet in a straight line away from the shooter, resulting in a reduction of perceived noise. Due to its six-hole design surrounding the central bore, it provides effective flash suppression that preserves the shooter’s night vision by disrupting the muzzle flash when firing in low lighting conditions.
