Introduced in 2020, the 6mm ARC (Advanced Rifle Cartridge) was designed to deliver excellent ballistic performance in AR15 platform rifles that rivals the extended range performance of larger rounds typically chambered in the larger AR10/LR308 style rifles. This flat shooting round makes a great choice for hunters and extended target shooters looking for predictable performance out of a feature packed rifle like the CMMG RESOLUTE Mk4.
