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

The legendary Huben K1, now in fast, flat-shooting .177 caliber: the most powerful semi-automatic bullpup on the market, built around a platform unlike any other PCP. At its heart is 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 high-capacity rotary magazine give you smooth control and fast follow-up shots in a true bullpup format. 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. The ergonomic black synthetic stock is built to withstand extreme temperatures, water and scratches. This model is compatible with the RTI · Hušh Suppressor.
