HUBEN GK1 AIR PISTOL – 5.5MM

LONG RANGE SHOOTING AIRGUN

The Huben GK1 is, without doubt, the most powerful semi-automatic Air Pistol on the market. A marvel of engineering and technology, its patented hammerless platform makes the GK1 very different from any other PCP Pistol. It can achieve a very high rate of fire, making the most out of its high capacity 19 round mag. The hammerless system is 100% mechanical and provides numerous advantages: high efficiency, zero vibrations, accuracy, and a wide variable power range.

The Huben GK1 was originally inspired by Gregor Kamenšek and then produced by Huben airguns hence the model GK1 after Gregor.

Huben GK1’s parts have always been made with top quality materials; nonetheless, since 2020, we have pushed our quality control to more demanding standards, guaranteeing excellent results.

HAMMERLESS ACTION

Fewer moving parts and vibration translates into unmatched accuracy and reliability. The trigger acts directly on the sear of the valve with no hammer strike. The valve, driven by a piston, is immediately opened by the pressure of the plenum.
ADJUSTABLE VALVE

Being able to modify at will the pressures you want to work with allows you to adjust velocities according to your energy or endurance needs.
HIGH-CAPACITY SEMI AUTO

The Huben GK1 is a semi-automatic bullpup air rifle that can shoot 19 rounds in quick, reliable succession before you need to reload the mag. It certainly packs a punch!
TWO STAGE TRIGGER

Because we hold extreme precision as our goal, we offer a crisp, two stage trigger with adjustable first stage for the most demanding shooters.
POWERFUL AND COMPACT

About us
As an emerging brand in the global air gun industry, HUBEN has been committed to the independent research and development, manufacturing, and sales of high precision and long-range air guns for fifteen years. After years of hard work, the revolutionary new structure of the PCP air gun has been successfully developed – the hammer-free semi-automatic excitation mechanism – and has applied for patents in different countries. The working principle of the hammer-free mechanism is as follows: After pulling the trigger to release the blockage, the air pressure pushes the piston back. Driven by the piston, the air valve opens the air passage, and the particles are pushed out. Then, cut off the air passage through the adjustable shut-off valve. After that, pushing the piston back pressure disappears, and the piston returns to the original position under the action of the spring to realize an automatic hook. Based on this system, HUBEN’s first PCP product, K1, has been the focus of many air gun enthusiasts since its inception.
Based on K1, another semi-auto pistol model GK1 was manufactured. Same high capacity magazine, adjustable power, and extreme air efficiency, you will find the real fantastic fun of shooting!
With more different models of products put into development, HUBEN products will bring you an unprecedented experience to satisfy your different needs!
