Tactical Match Barrel with .223 Wylde Chamber
The 16-inch Tactical Match barrel is forged from 4150 Chrome Moly Vanadium steel and finished with a phosphate coating for corrosion resistance and barrel longevity. The .223 Wylde chamber is engineered to safely fire both .223 Remington and 5.56 NATO ammunition while maintaining match-grade accuracy potential, combining the pressure safety margin of 5.56 NATO with the precision tolerances of .223 Remington. The 1:8 twist rate stabilizes a wide range of bullet weights from 55 to 77 grains, making this barrel equally capable with lightweight range ammunition and heavier match projectiles. This versatility allows precision shooters to dial in their preferred loads without sacrificing reliability or accuracy.
15" Freefloat M-Lok Handguard
The 15-inch freefloat M-Lok handguard is machined from aircraft-grade aluminum for exceptional strength-to-weight ratio and heat dissipation. The black anodized finish provides corrosion resistance and a professional appearance that pairs with any build aesthetic. M-Lok slots run the length of the handguard for direct accessory mounting without bulky rail sections, keeping your upper lightweight and streamlined. The freefloat design isolates the barrel from handguard contact, maximizing accuracy potential by eliminating point-of-impact shifts caused by sling tension or support hand pressure. The extended 15-inch length provides maximum mounting flexibility for bipods, lights, grips, and other accessories while covering nearly the entire barrel for a modern, competition-ready profile.
Upper Receiver and Gas System
The 7075-T6 aluminum upper receiver delivers superior strength and durability compared to standard 6061 aluminum, making it ideal for precision applications where dimensional stability matters. The anodized finish protects against wear and corrosion during extended use. M4 feed ramps guide cartridges smoothly from magazine to chamber, enhancing reliability across a variety of magazines and ammunition types. The carbine-length gas system with micro low-profile gas block ensures consistent gas delivery for reliable cycling while maintaining a clean, snag-free profile under the handguard.
Ready for Assembly
This upper build kit includes all essential components for final assembly: the Tactical Match barrel, freefloat M-Lok handguard, upper receiver, micro low-profile gas block, and GI birdcage flash hider. The standard flash hider provides effective flash suppression for range and field use without adding unnecessary weight or length. All components are precision-manufactured for proper fitment and are ready for gunsmiths to complete assembly with their preferred bolt carrier group, charging handle, and other finishing components.
