The design of the EPeS M60/PKM hop-up unit focuses on the geometry between the chamber and the lips of the hop-up bucking. In M60 and PKM airsoft guns, the compatibility between the lips and the hop-up unit often causes feeding issues and gun jams. The EPeS M60/PKM unit aims to solve these problems. After extensive development and testing, the result is a universal hop-up unit geometry that fits almost all hop-up buckings currently available on the market.
Another important factor affecting the performance and operation of an AEG is the correct positioning of the hop-up chamber between the outer barrel housing and the gearbox. The included O-rings in different sizes ensure proper axial alignment.
This hop-up chamber is designed to deliver the best possible performance and reliability, ensuring optimal function in all conditions.
