The magazine is made of high-strength polymer and is designed with grips for the spring on both sides making it simple to load. The 10-round version of the magazine is proportionate in size to the centerfire version's mag to maintain the authentic look of the 9mm MP5s magazine.

The .22 caliber HK MP5 A5 operates on a blowback system and the bolt holds open when the magazine empties. The front sight is adjustable for elevation and comes with interchangeable posts. The rear sight is adjustable for windage and elevation. Its safety switch rotates in the same manner as the 9 mm MP5.
