3. Magazines designed or manufactured for both centrefire calibre semiautomatic rifles and other (non-semiautomatic) rifles
Magazines designed to contain centrefire cartridges and designed or manufactured for use in a semiautomatic rifle are limited to five cartridges. However, magazines designed to contain centrefire cartridges and designed or manufactured for use in a rifle other than a semiautomatic or automatic rifle, do not have a regulated capacity. Magazines that are designed or manufactured for use in both semiautomatic rifles and other (non-semiautomatic) rifles are subject to the semiautomatic rifle limit of five cartridges.
Example:
Remington model 7615 pump action rifle chambered for 223 Remington caliber:
the 10 round magazine is prohibited
the five round magazine is unregulated
