  • Very precise, high firing rate, robust and reliable
  • Magazine is too small, a kind of drum magazine would be desirable 😁

Really a great weapon, which will attract attention everywhere thanks to automatic firing. You empty the magazine in 4 seconds 🤣🤣🤣
The cartridges last for 3 to 6 magazines. However, after the 3rd magazine, a decrease in performance is noticeable.
I once had the opportunity to try the original, and when I saw this, my eyes almost popped out of their sockets. This air rifle is, except for a few details, like the original.
Please, ask the manufacturer for a rifled barrel and pellet shooting 😎🤩

  • Option to switch between automatic and single shots
  • Real controls
  • Really great fun with automatic shooting
  • Really large ammunition consumption
  • Magazine only holds 30 rounds. It would need a larger capacity.
  • It is not possible to do a real disassembly, even though the components are there. A Phillips screwdriver is needed, and first the tension lever must be loosened.
  • Worse accuracy, more towards cans than a target

Where can I shoot an air rifle

This article should be taken as informative only as it is based on the act issued and applicable only in the Czech Republic.
After acquiring your first air rifle, you probably wondered where you could actually shoot it. Whether it's a classic spring gun, a CO2-powered pistol or a high-performance PCP air rifle, the same rules apply.
