The 6mm ARC (Advanced Rifle Cartridge) was built to bring exceptional ballistic performance to the AR-15 platform, delivering extended range capabilities that rival larger calibers traditionally reserved for AR-10/LR308 rifles. When paired with the lightweight and low-recoil Br4 platform, the result is a smooth-shooting rifle that's perfect for hunters and long-range target shooters alike. Whether you're tracking game or punching paper at distance, the flat-shooting nature of 6mm ARC combined with the Br4's precision engineering offers reliable, predictable performance shot after shot.

This package includes (2) CMMG 10-round magazines, ensuring compliance and reliability out of the box
