Huben K1 Special Edition Air Rifle · Cal .177 (4.5mm)

The legendary Huben K1, now in fast, flat-shooting .177 caliber and presented in a refined Special Edition with carbon fiber and walnut.

The Special Edition has the exact mechanism and performance of the famous K1 with black synthetic stock, upgraded with a high-quality carbon fiber shroud and a beautifully crafted wooden stock. The result is a lighter, more elegant and perfectly balanced K1 that preserves what makes this platform unique: precise, reliable semi-automatic fire in a true bullpup format.

Beneath its refined exterior lies the patented hammerless mechanical system that defines the K1. It is 100% mechanical, with zero vibrations, exceptional efficiency and a remarkably wide power range, allowing the K1 to deliver consistent accuracy at any power level. A very high rate of fire and a 19-shot rotary magazine give you smooth control and fast follow-up shots.

In .177, the K1's light pellets leave the barrel fast and fly flat, making it an excellent choice for pest control, target shooting and plinking, and for shooters in countries with lower power limits, where .177 is often the most effective caliber.

Huben K1 parts have always been made from top quality materials, and since 2020 our quality control has been pushed to even more demanding standards.

This is the K1 in a more refined form: precision caliber, timeless materials.

This model is compatible with the RTI · Hušh Suppressor.

Note: Crafted from natural walnut, each wooden stock showcases its own beautiful grain, color, and shading, making every piece unique and can be slightly different from the images shown.
