"Satellite" Barrel Construction
The 16.5-inch "Satellite" barrel is machined from 4150 Chrome Moly Vanadium steel, a proven material choice for strength and durability under demanding shooting conditions. The medium profile provides a balanced weight distribution, reducing muzzle heaviness while maintaining sufficient rigidity for consistent accuracy. The nitride finish enhances surface hardness and provides superior corrosion resistance, ensuring consistent performance across extended shooting sessions and varied environmental conditions. The 1:7 twist rate is engineered to stabilize a broad spectrum of projectile weights, from lightweight 55-grain bullets for high-velocity applications to heavier 77-grain match projectiles for precision shooting, supporting versatility across training, competition, and recreational shooting applications.
Mid-Length Gas System and Upper Receiver
The mid-length gas system is optimized for 16-inch and longer barrels, providing enhanced recoil management and smoother cycling compared to carbine-length systems. This gas system length reduces felt recoil and muzzle rise while supporting more consistent extraction and ejection, contributing to improved shooter comfort and faster follow-up shots during rapid-fire sequences. The micro low-profile gas block provides a streamlined profile that fits cleanly under freefloat handguards while ensuring dependable gas system function. The 7075-T6 aluminum upper receiver offers exceptional strength-to-weight ratio, reducing overall upper weight while maintaining structural integrity for reliable long-term performance. The anodized finish provides enhanced corrosion resistance and a durable surface for demanding shooting applications.
Bolt Carrier Group and Charging Handle
The included complete bolt carrier group is forged from 9310 alloy steel, a material selected for its exceptional strength and fatigue resistance under the high-pressure cycling demands of the AR-15 platform. The nitride finish provides enhanced surface hardness and corrosion resistance, reducing friction for smoother operation while supporting reliable long-term performance across thousands of rounds. This treatment creates a hard, durable surface that improves wear characteristics and ensures consistent cycling and extraction performance. Paired with a mil-spec AR-15 M4 charging handle, the complete upper ensures smooth, dependable operation and broad compatibility with aftermarket upgrades and accessories.
Keymod Freefloat Handguard System
The 15-inch Keymod freefloat handguard is constructed from lightweight 6061-T6 aluminum, balancing structural rigidity with reduced weight for improved handling and balance. The freefloat design isolates the barrel from external contact, supporting enhanced accuracy potential by eliminating pressure points that can affect barrel harmonics during firing. The Keymod attachment system offers lightweight mounting points for lights, laser devices, vertical grips, bipods, and other accessories at multiple positions along the rail, allowing shooters to configure the platform to match their specific mission requirements or shooting style. The extended 15-inch length provides ample mounting space and covers most of the barrel for a modern, streamlined appearance while keeping overall weight minimized.
Muzzle Device and Complete Upper Design
The included birdcage flash hider effectively reduces muzzle flash, improving visibility and target tracking during rapid-fire strings and low-light shooting scenarios. This proven design completes a comprehensive upper assembly engineered for precision, reliability, and versatile performance across diverse shooting applications. The combination of medium-profile barrel, mid-length gas system, nitride-finished bolt carrier group, and freefloat handguard delivers a complete platform ready for integration with your preferred lower receiver.
Follow safe handling practices and manufacturer instructions for assembly and use. Ensure compliance with all applicable federal, state, and local laws. This upper is chambered in 5.56 NATO. Complete upper pairs with lower receiver—see configuration for complete firearm options.
