The 6mm ARC cartridge is based on the 6.5 Grendel case necked down for 6mm bullets. Good News! If you already have a rifle chambered in 6.5 Grendel, the ONLY thing you need to change is the barrel. Everything else - bolt, magazines, gas system - is compatible with 6mm ARC.
- Fits standard AR-15 rifles & Short/Mini action bolt rifles
- 30-degree case shoulder for reliable feeding
- Short, squat case profile similar to the 6mm PPC, one of the most accurate benchrest cartridges ever
- SAAMI spec cartridge, so NOT a fly-by-night Wildcat!
