Huben | K1 Air Rifle
from $1,969.00
SHIPPING NOW
The Huben K1 rifle is one of the most accurate and powerful semi-automatic PCP bullpups on the market. A marvel of engineering and technology, its patented hammerless platform makes the K1 very different from any other PCP. It is able to achieve a very high rate of fire, making the most of its high-capacity 17/19-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 K1 rifle was initially designed to shoot accurately at extreme power levels, with long range shooting and hunting in mind. However, the last version of the K1 has become a more flexible design, becoming an accurate gun at any power level.
Huben K1’s parts have always been made with top-quality materials; nonetheless, since 2020, they have pushed their quality control to more demanding standards, guaranteeing excellent results.
The Huben K1 features a very ergonomic black stock made of hardy synthetic material able to withstand most extreme situations and environments (extreme temperatures, water, scratches, etc...)
