Out of the box, the Supreme includes a 10-round Magpul^® PMAG^® with a 5-round limiter to comply with hunting regulations in certain parts of the country. For those who favor less reloading at the range, additional capacity is available using MSR-style magazines. In time, expect a plethora of caliber options never seen in the category to suit hobbyists, hunters, and protectors alike. The Supreme’s use of a detachable box magazine eliminates the bullet restrictions inherent to tube magazine designs.
