Heckler & Koch MP5 K-PDW 4.5mm CO2 Airgun with Blowback

The Heckler & Koch MP5 K-PDW 4.5mm CO2 is a recreational airgun inspired by the legendary German submachine gun used worldwide by special forces, border guards, and tactical police units. Built for high-speed target shooting and plinking, it combines authentic handling with impressive performance.

Modular & Lightweight Construction

Like the real firearm, the outer receiver, folding stock, and pistol grip are crafted from tough impact-resistant polymer, maintaining a manageable weight of just 1,635 grams. Internal critical components—including the inner barrel, CO2 valve, trigger assembly, winged safety, and 41-round magazine—are constructed from solid metal for long-term reliability.

The side-folding buttstock can be locked back or completely detached by removing two pushpins without any tools, making the replica exceptionally compact for transport or close-quarters target shooting. It also features a top 22mm Picatinny rail for mounting red dot optics, a removable flash hider, and a front vertical handgrip with a tactical sling attachment point.

Blowback Recoil System & CO2 Power

Equipped with a crisp Blowback system, the bolt cycles vigorously backward with every pull of the Double Action Only (DAO) trigger, providing realistic recoil and satisfying feedback. Powered by a single 12g CO2 cartridge installed in the rear frame, it fires 4.5mm steel BBs at velocities up to 145 m/s (~475 fps), yielding approximately 80 consistent shots per cartridge.

Key Features

  • Licensed H&K Design: Original submachine gun ergonomics and markings
  • Hard-Hitting Blowback: Simulates realistic cycling action and recoil impulse
  • Versatile Stock System: Foldable or quickly detachable for maximum mobility
  • Picatinny Top Rail: Ready for red dot sights and tactical optics
  • Convenient Loading: 41-round drop-free metal BB magazine with gravity-feed lock feature
  • Ambidextrous Handling: Winged safety lever and central magazine release switch
