Match Grade Barrel Construction

The 16-inch Match Grade barrel is machined from polished 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 55-grain to 77-grain bullets, supporting versatility across training, competition, and precision shooting applications.

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 (.750) 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 inclusion of M4 feed ramps enhances feeding reliability, supporting smooth chambering across diverse ammunition types and reducing potential feeding issues. The anodized finish provides corrosion resistance and a durable surface for demanding shooting applications.

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.

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 while maintaining a compact profile, making it suitable for a wide range of shooting applications from recreational to competitive use.

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. This kit includes upper components only—BCG, charging handle, LPK, and lower receiver sold separately.
