The CMMG FourSix 10-round magazine is designed exclusively to feed the 4.6x30mm cartridge through the CMMG FourSix upper receiver paired with a CMMG Mk4 or standard AR15 lower. Features the same profile and size as the 40-round FourSix magazines, with exterior dimensions similar to most 30-round 5.56mm AR15 magazines. Patent-pending design seats into a standard AR15-sized magwell for seamless compatibility.
