About 338 ARC

The 338 ARC cartridge was developed to combine AR-15 platform parts compatibility with a larger bore caliber. According to CMMG, 338 ARC is designed to offer sub- and supersonic versatility similar to 300 Blackout while delivering more energy on target and requiring less gas system tuning when transitioning between suppressed and unsuppressed configurations. The cartridge uses the same bolt as 6.5 Grendel AR-15 builds, maximizing parts compatibility across platforms.
