.223 Wylde Chamber Versatility

The .223 Wylde chamber is designed to safely fire both .223 Remington and 5.56 NATO ammunition while maintaining match-grade accuracy potential. This hybrid chamber specification combines the pressure safety margin of 5.56 NATO with the tighter tolerances of .223 Remington, giving you the flexibility to choose from a wide range of factory loads and handloads. Whether you're running budget plinking ammo or precision match rounds, the .223 Wylde chamber delivers consistent performance across the spectrum.

4150 CMV Barrel with Phosphate Finish

The 16-inch barrel is forged from 4150 Chrome Moly Vanadium steel, a material trusted for its strength and durability under high round counts. The phosphate coating provides corrosion resistance and wear protection, extending barrel life even in adverse conditions. The 1:8 twist rate stabilizes a broad range of bullet weights from 55 to 77 grains, making this barrel equally capable with lightweight varmint loads and heavier match projectiles. The carbine-length gas system pairs perfectly with the 16-inch barrel for balanced cycling and recoil management.

M-Lok Handguard and Upper Assembly

The freefloat M-Lok handguard is machined from 6061-T6 aluminum for lightweight rigidity and heat dissipation. M-Lok slots provide direct mounting points for accessories without bulky rail sections, keeping your build streamlined and weight-forward balance optimized. The freefloat design isolates the barrel from handguard pressure for improved accuracy potential. The 7075-T6 aluminum upper receiver features M4 feed ramps that guide cartridges smoothly from magazine to chamber, enhancing reliability with a variety of magazines and ammunition types.

Complete Internals and Stock

This kit includes a complete bolt carrier group constructed from 9310 alloy steel with a nitride finish for exceptional hardness and corrosion resistance. The mil-spec AR-15 M4 charging handle provides reliable manipulation, while the special operations stock completes the lower assembly for a ready-to-configure rifle. The micro low-profile gas block maintains a clean, snag-free profile under the handguard while ensuring consistent gas delivery to the carrier.
