Barrel and Gas System

The barrel runs 16 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 carbine-length system, running a stainless steel carbine-length gas tube and a premium adjustable low-profile gas block sized to a .750-inch diameter.

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 15-inch K-style handguard, an ultra-lightweight minimalist design using an M-LOK attachment system along its length. This handguard does not include anti-rotation tabs.

Muzzle Device

Capping the muzzle is a Delta Team Tactical Plan B Trident flash hider, machined from 17-4 H1150 stainless steel and finished in nitride, built in a three-prong trident design with a Plan B-style suppressor mounting interface. It threads onto the barrel's 1/2x28 pattern.
