The BIG little cartridge that packs a punch!
Built for hard-hitting subsonic performance, the .338 ARC delivers up to 1.5 times the energy of the .300 Blackout Subsonic. Engineered for optimal pressure and consistency, it ensures reliable cycling with both supersonic and subsonic loads. Available with a 307-grain SUB-X bullet in the SUBSONIC line and a 175-grain HP in the BLACK series, the .338 ARC stands as the ultimate .338 cartridge designed specifically for the AR-15 platform.
At every stage of our .338 ARC builds, craftsmanship takes center stage. We hand-select components with proven track records and rely on battle-tested assembly methods to deliver uncompromising quality. Each upper is torqued precisely to Mil-Spec, verified for flawless headspace, and fine-tuned with receiver truing and barrel bedding for exceptional accuracy. Before leaving our shop, every rifle endures a full test-fire to confirm rock-solid reliability. The result is a .338 ARC that embodies peak precision, durability, and performance—ready the moment you are.
