Barrel and Gas System

The 20-inch Bear Creek Arsenal barrel is machined in an HBAR heavy profile, a design that carries extra mass down the length of the barrel to help manage heat and hold accuracy across longer strings of fire. It's finished in Black Nitride for wear and corrosion resistance, and its 1:7 twist rate is on the faster end for .22 ARC, giving it the stabilization needed for a wide range of bullet weights rather than just the lighter, faster-twist-oriented projectiles. The rifle-length gas system runs through a stainless steel gas tube and a micro low-profile steel gas block with a .750-inch diameter, matched to the barrel's .750-inch gas journal. At the muzzle, 1/2x28 threads carry the included Crown muzzle brake, made in the USA and finished in Nitride, secured in place with the supplied 1/2-inch black crush washer.

Upper Receiver and Handguard

The upper receiver is machined from 7075-T6 aluminum, chosen for its strength-to-weight balance on AR-pattern uppers, and finished in black anodizing for durability. M4 feed ramps are cut into the receiver, and it arrives with the forward assist assembly and the ejection port door, rod, and spring already in place. Over the barrel and gas system sits a 15-inch K-style handguard built in an ultra-lightweight, minimalist free-float design with M-LOK compatibility, finished in FDE Cerakote to contrast against the black upper receiver. Because it's built without anti-rotation tabs, the handguard keeps a cleaner, lower-profile look along the barrel compared to tabbed designs.
