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.
➲ Slim M-LOK Handguard
Your AR-15 handguard has huge implications in terms of how much you enjoy your shooting experience. Our M-LOK handguard offers more than just the accuracy enhancements that come with a free-floating rail. It features a detached style picatinny top rail that sits flush with M4 flat top receivers allowing you to have more space for optics and back up iron sights. The slim profile is comfortable to grip while still allowing enough room for low profile gas blacks underneath. This AR-15 handguard is machined from 6061 aluminum, has a hard coat anodized black finish, and generously sized M-LOK cuts for air circulation.
