Barrel and Gas System

The barrel runs 16 inches long, chambered in .223 Wylde and finished in black nitride with a heavy profile and straight fluting to shed weight. It carries a 1:8 twist rate and a 1/2x28 muzzle thread. Gas cycles back to the action through a carbine-length system, running a stainless steel carbine-length gas tube and a micro low-profile steel gas block.

Upper Receiver and Handguard

The upper receiver is machined from 7075-T6 aluminum and finished in black anodizing, cut with M4 feed ramps for smooth feeding and fitted with an AR-15 forward assist assembly. The ejection port carries a standard door with its rod and spring installed. Over the barrel sits a 15-inch Trinity Force KMX handguard, a free-float design finished in black, using a KeyMod attachment system with a full-length Picatinny top rail and lightweight ventilation cutouts along its length.

Muzzle Device

Capping the muzzle is an A2 GI birdcage flash hider, threaded to match the barrel's 1/2x28 pattern and secured with the included 1/2-inch black crush washer.
