Umarex H&K MP5 K-PDW — 4.5mm BB Rifle (5.8159)
The Umarex H&K MP5 K-PDW 4.5mm BB Rifle brings the iconic MP5 profile into a compact, CO₂-powered package. With realistic blowback action and rapid semi-auto fire from dual 12g CO₂ capsules, it delivers convincing recoil and handling for training, tactical drills, or serious non-lethal home defense practice. The folding stock and compact dimensions make it agile in tight spaces while still feeling like the real thing.
Controls and ergonomics are built for the modern shooter: ambidextrous controls, a Picatinny rail for optics or lights, and a drum-style sight that balances quick target acquisition with accuracy. For security professionals, instructors, and enthusiasts who want authentic MP5 handling without live firearms, the K-PDW is a hard-working, user-friendly option.
