Nitride Barrel Performance and Versatility
The 6-inch nitride-finished steel barrel delivers exceptional corrosion resistance and surface hardness for long-term durability under demanding conditions. The nitride treatment penetrates the steel, providing superior wear resistance while maintaining dimensional accuracy and precision. With a 1:7 twist rate, this barrel ensures optimal stability across a wide range of .300 Blackout ammunition options, from lightweight supersonic rounds for maximum velocity to heavy subsonic loads ideal for suppressed applications. The pistol-length gas system paired with a micro low-profile gas block provides efficient gas operation and reliable cycling across the full spectrum of .300 Blackout loads.
Enhanced Feeding Reliability
The 7075-T6 aluminum upper receiver features M4 feed ramps for improved feeding reliability with various ammunition types and bullet profiles. This enhancement is particularly valuable in .300 Blackout applications where projectile shapes can vary significantly between supersonic and subsonic loads. The anodized finish adds strength and longevity, resisting wear and corrosion even under demanding use. The upper's forged construction provides exceptional dimensional stability, ensuring proper alignment and consistent function with your chosen bolt carrier group and charging handle.
M-Lok Modularity and Compact Design
The freefloat M-Lok handguard crafted from 6061-T6 aluminum offers lightweight strength and versatile mounting options for lights, lasers, grips, and other accessories. The M-Lok interface allows quick, secure attachment of accessories exactly where you need them, ensuring you can configure this upper to match your intended application. The freefloat design eliminates handguard contact with the barrel for improved accuracy and thermal management, while the lightweight construction keeps the overall build maneuverable and easy to handle in close quarters.
