Due to the immense popularity of last year's special edition banana magazine, we're thrilled to reintroduce it with a fresh twist. This time, it's here to stay. Enjoy! The Amend2 30-round magazine is a robust and dependable AR15/M4/M16 magazine chambered in 5.56x45mm NATO (.223 Remington), crafted from advanced polymer material. It offers a lightweight, durable and superior alternative to the standard M4/M16 USGI aluminum magazine.
