The AC-Unity HK MP5 30RDS window magazine cal. 9x19mm is a lightweight, impact resistant and highly reliable magazine for all 9mm HK MP5, SP5, MP5K, SP5K, HK94, MKE, MP5RS and clones taking standard MP5 magazines.

Made of an advanced polymer-resin/granulate that is light weight and extremely shock resistant. This polymer is exclusive to AC-Unity and gives these magazines a huge edge in weight and durability. The body is impact resistant through a wide range of temperatures. Metal parts are hardened and corrosion resistant. Carbon wire spring has a lifetime warranty against corrosion and will not degrade from use or loaded storage, and the double-sided clear window allows to see the rounds left.

These magazines have a long lifetime and can survive maximum temperature fluctuations from -60°C to +60°C. The material composition allows for long time storage, even when fully loaded, and the magazine lips will stay in the correct position and not spread or balloon because of spring pressure.
