18-Inch Barrel with Rifle-Length Gas System: The 18-inch government profile barrel provides optimal velocity for 5.56 NATO ammunition, extracting maximum performance from the cartridge for improved energy delivery and flatter trajectories. The 1:7 twist rate ensures optimal projectile stability and accuracy with heavier bullets commonly used in precision shooting. The rifle-length gas system—the longest available for AR-15 platforms—enhances cycling efficiency with reduced felt recoil, smoother operation, and minimal carrier velocity for decreased wear on components and improved longevity.
Premium 15-Inch M-LOK Freefloat Handguard with Integrated Features: The 15-inch M-LOK freefloat handguard provides extensive mounting surface for bipods, lights, lasers, and accessories while eliminating barrel contact for improved accuracy. The integrated handstop offers a natural hand positioning reference for consistent grip placement and enhanced control during rapid fire. Partial Picatinny rail sections allow direct mounting of traditional accessories without M-LOK adapters, while anti-rotation tabs ensure secure, movement-free handguard installation. This combination provides versatile attachment options for various shooting applications and accessory configurations.
Micro Low-Profile Gas Block & Premium Upper Receiver: The micro low-profile .750 O.D. gas block is crafted from durable steel with phosphate finish for corrosion resistance and longevity. The streamlined design fits cleanly under the handguard for a sleek profile without visible gas block protrusion. The 7075-T6 forged aluminum upper receiver provides superior strength and robustness compared to 6061 aluminum, with anodized finish ensuring long-term durability and wear resistance. The forged construction delivers consistent quality and reliability for demanding precision shooting applications.
Plan B Sentinel Caged Flash Hider & Complete Configuration: The Plan B Sentinel caged flash hider features a unique design that minimizes muzzle flash while maintaining a sleek profile, improving shooter visibility during rapid fire and low-light conditions. The caged construction also protects the flash hider from impact damage while offering quick-detach capability for certain suppressor systems. This complete upper build includes bolt carrier group, charging handle, and all necessary components, making it a functional choice for gunsmiths and shooters looking to build a solid, precision-ready AR-15 system without sourcing additional parts.
