Can you use 6mm ARC in states with caliber restrictions?

April 5, 2026

Quick Answer

Some states have caliber restrictions, but the 6mm ARC is generally considered a variant of the 6.5 Grendel, which might be allowed depending on specific state laws. However, it's essential to check local regulations before hunting with a 6mm ARC in a restricted state. The rifle's configuration and magazine capacity may also impact its acceptability.

Understanding 6mm ARC Restriction Concerns

The 6mm ARC, or Advanced Rifle Cartridge, is a cartridge designed for the AR15 platform. It shares many similarities with the 6.5 Grendel, including a similar case length and weight. This similarity may lead to confusion about its acceptability in states with caliber restrictions. However, the 6mm ARC is a distinct cartridge with its own ballistic profile and performance characteristics.

Checking Local Regulations

When hunting in states with caliber restrictions, it’s crucial to research local laws and regulations regarding the 6mm ARC. This may involve contacting the state’s wildlife agency or consulting online resources. In some states, the 6mm ARC may be considered a restricted cartridge, while in others, it may be allowed for hunting certain species. For example, the state of California has specific regulations regarding the 6.5 Grendel, but it’s unclear whether the 6mm ARC would be subject to the same restrictions.

AR15 Configuration and Magazine Capacity Considerations

In addition to the cartridge itself, the AR15 rifle’s configuration and magazine capacity may impact its acceptability in states with caliber restrictions. Some states may have laws regarding the type of magazines that can be used with specific calibers. Rifles with high-capacity magazines may be subject to additional restrictions, even if the cartridge itself is allowed. Hunters should familiarize themselves with local laws regarding magazine capacity and rifle configuration to avoid potential issues during hunting trips.
