Due to the massive popularity of the special edition banana magazine we did last year, we decided to bring it back with a slightly different design. This time, for good. Eat up!The Amend2® 30 round magazine is a sturdy, reliable 5.56x45 NATO (.223 Remington) AR15/M4/M16 magazine made of an advanced polymer material. It is a light, durable and excellent alternative to the standard M4/M16 USGI aluminum magazine.
