.223 Wylde Chamber for Ammunition Flexibility

The .223 Wylde chamber is engineered 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 precision tolerances of .223 Remington, giving you the flexibility to run everything from budget training ammo to precision match loads. Whether you're running drills at the range or pursuing tighter groups on paper, the .223 Wylde chamber delivers consistent performance across the ammunition spectrum.

4150 CrMoV M4 Profile Barrel

The 16-inch M4 profile barrel is forged from 4150 Chrome Moly Vanadium steel, a material trusted for its strength and durability under high round counts. The phosphate finish provides corrosion resistance and wear protection, extending barrel life even in demanding conditions. The 1:7 twist rate stabilizes a wide range of bullet weights from 55 to 77 grains, making this barrel equally capable with lightweight plinking rounds and heavier tactical projectiles. The M4 profile balances weight distribution for comfortable handling while maintaining barrel rigidity for accuracy.

15" M-Lok Slant-Pro Handguard

The 15-inch M-Lok Slant-Pro handguard is machined from 6061-T6 aluminum for lightweight rigidity and heat dissipation. The slant-cut design extends usable rail space nearly to the muzzle device, maximizing mounting options for lights, lasers, grips, and other accessories. M-Lok slots provide direct attachment points without bulky rail sections, keeping your build streamlined and maintaining weight-forward balance. The black anodized finish offers a sleek, professional appearance while protecting against wear and corrosion.

Complete Internals and Flash Suppression

This upper includes a complete bolt carrier group constructed from 9310 alloy steel with a nitride finish for exceptional hardness and corrosion resistance. The AR-15 M4 charging handle provides reliable manipulation for tactical and training scenarios. The micro low-profile gas block maintains a clean, snag-free profile under the handguard while ensuring consistent gas delivery to the carrier. Topped with a GI birdcage flash hider, this upper reduces muzzle flash for improved visibility during rapid-fire sequences and low-light engagements.
