The Huben K1 is an exceptional semi-automatic PCP air rifle, representing a significant innovation in airgun technology. It's specifically crafted for the demanding technical shooter who requires superior precision, unwavering reliability, and adaptable modular performance.
Available to UK buyers in .22 (5.5mm), .25 (6.35mm) and .30 (7.62mm) calibre, the K1 delivers consistent power across every shot — making it one of the most accurate and capable PCP air rifles on the British market today. For UK shooters in England and Wales, the rifle can be configured to shoot comfortably below the legal 12 ft·lb limit — no Firearm Certificate required.
The answer lies beneath the stock: a fully mechanical hammerless firing system, patented worldwide and exclusive to Huben.
Unlike conventional PCP designs that rely on a firing pin (which generates vibrations and inconsistency), the K1's hammerless platform fires without mechanical vibrations, providing consistency between multiple shots.
The K1 is supplied with a precision built-in regulator, adjustable between 120–220 BAR, giving you complete control over muzzle energy output.
The K1 collection includes standard, special edition, and lightweight models and all variants are optimized to meet UK legal standards.
Detailed specifications for each model are provided in both ft-lb and imperial/metric units for convenient reference.
The standard K1 is the entry point into Huben's hammerless platform. Available in .22 and .25 calibres, and now also in the desirable .30 calibre (7.62 mm), this is the rifle that has established Huben's reputation in the air rifle shooting community.
The Special Edition features the complete K1 hammerless mechanism, combined with a hand-finished walnut stock, for the shooter who demands both performance and excellence.
The Wolfiek Lite replaces the standard synthetic stock with a full carbon fibre chassis, reducing overall weight without sacrificing a single millimetre of barrel length or accuracy.

A Pre-Charged Pneumatic (PCP) air rifle utilizes a regulated, onboard reservoir to store compressed air. This reservoir is filled using either a hand pump or a compressor, and its design delivers consistent power throughout the entire magazine.
In England and Wales, air rifles with a muzzle energy of 12 ft·lb (or about 16 Joules) or less are not requiring a Firearm Certificate. However, these rules do NOT apply to higher-powered configurations or to buyers located in Scotland.
