The BIG Little Cartridge That Hits Hard
Compact. Powerful. Purpose-Built.
The .338 ARC is engineered to dominate the subsonic game, delivering up to 1.5x more energy than .300 Blackout Subsonic—all while maintaining flawless cycling with both super and subsonic loads.
Whether suppressed or unsuppressed, the .338 ARC’s performance is anchored by precision pressure control and purpose-built bullet options:
307-grain SUB-X in the Subsonic line
175-grain HP in the BLACK series
This is the only .338 cartridge specifically optimized for the AR-15 platform—offering power, precision, and reliability in a compact package.
Craftsmanship at Every Step
We don’t just assemble rifles—we build them for serious performance. Every .338 ARC upper is:
Hand-assembled with premium, combat-proven components
Torqued to Mil-Spec, checked for perfect headspace
Receiver-trued and barrel-bedded for peak accuracy
Test-fired and inspected before it leaves our bench
The result: a firearm that’s deadly accurate, cycle-reliable, and built to last.
