Barrel and Gas System

The barrel runs 14.5 inches long, chambered in 5.56 NATO and built from 4150 chrome moly vanadium steel with a nitride finish and medium profile. It carries a 1:7 twist rate and a 1/2x28 muzzle thread. Gas cycles back to the action through a mid-length system, running a stainless steel mid-length gas tube and a micro low-profile steel gas block sized to a .750-inch journal.

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 .223/5.56 door with its rod and spring installed. Over the barrel sits a 12.5-inch tubular handguard machined from aluminum with a 1.77-inch internal diameter, free-floated and built in a Suppressor-Ready design, using an M-LOK attachment system along its length.

Muzzle Device

Capping the muzzle is an A2 GI birdcage flash hider, compatible with both 5.56 NATO and .223 Remington. It threads onto the barrel's 1/2x28 pattern and is secured in its final timed position with a 1/2-inch black crush washer.
