Match Grade Barrel Construction
The 16-inch Match Grade barrel is machined from 416R stainless steel, a premium material choice specifically selected for precision shooting applications. 416R stainless steel offers excellent dimensional stability, superior bore consistency, and enhanced accuracy potential compared to standard chrome moly barrels. The polished finish provides a smooth, corrosion-resistant surface while the material properties support tight tolerances and consistent performance across extended shooting sessions. The M4 profile provides a proven balance of weight distribution and barrel rigidity for reliable operation. The 1:8 twist rate is optimized for stabilizing a wide range of 5.56 NATO 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.
Carbine-Length Gas System and Upper Receiver
The carbine-length gas system is a proven standard for 16-inch barrels, offering reliable cycling performance and consistent extraction and ejection across varied ammunition types. The micro low-profile gas block provides a streamlined profile that fits cleanly under freefloat handguards while ensuring dependable gas system function and enhanced usability. 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, ensuring the upper maintains both functional performance and aesthetic appeal through extended use.
Bolt Carrier Group and Charging Handle
The included 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 charging handle, the complete upper ensures smooth, dependable operation and broad compatibility with aftermarket upgrades and accessories.
Keymod Freefloat Handguard System
The 15-inch freefloat Keymod handguard is constructed from lightweight 6061-T6 aluminum, balancing structural rigidity with reduced weight for improved handling and balance. The black finish provides an attractive, durable surface that resists wear and environmental degradation. The freefloat design isolates the barrel from external contact, supporting enhanced accuracy potential by eliminating pressure points that can affect barrel harmonics during firing—particularly beneficial when paired with the Match Grade stainless steel barrel. The Keymod attachment system offers lightweight mounting points for lights, laser devices, vertical grips, bipods, and other accessories at multiple positions along the rail. The extended 15-inch length provides ample mounting space and covers most of the barrel for a modern, streamlined appearance while supporting versatile accessory configuration.
Stainless Steel Muzzle Device
The included stainless steel birdcage GI-type flash hider effectively reduces muzzle flash, improving visibility and target tracking during rapid-fire strings and low-light shooting scenarios. The stainless steel construction complements the stainless barrel material and provides excellent corrosion resistance for long-term durability. The proven GI-type design delivers reliable flash suppression and effective muzzle control while maintaining a compact profile, making it suitable for a wide range of shooting applications from recreational to competitive use.
