Armalite’s CK-4 code denotes a small-batch National Match series featuring a precision-lapped Krieger barrel. The 24-inch heavy contour tube is free-floated inside a cylindrical aluminum handguard that carries rail segments at the 12, 3, 6, and 9 o'clock positions for accessories.
The forged 7075-T6 receivers are hard-anodized and include a slick-side upper without a forward assist, increasing stiffness for improved shot-to-shot consistency. A two-chamber multi-port muzzle brake threaded 5/8-24 TPI tames recoil and keeps the rifle on target.
The National Match two-stage trigger breaks at roughly 4.5 lb, giving a crisp, repeatable pull suited to precision work. An adjustable fixed stock offers wheel-adjustable cheek height, length of pull, and a rear monopod spigot, allowing the shooter to tailor fit and stability.
Sighting options are extensive: the included BEC Gold Label 4-16×50 scope mounts to the flat-top Picatinny rail, while the detachable carry-handle rear sight with built-in spirit level and folding BUIS give redundant iron sight capability.
This AR-10 platform delivers 7.62 NATO performance in a configuration equally at home guarding the house or punching tight groups at the range.
