Epes M60/RPK CNC Hop Unit

A high-end hop-up chamber for M60 and PKM that will give your machine gun maximum performance and precision. Our unique chamber design uses the standard AEG hop-up bucking but provides flawless construction and many upgrades at the same time. Thanks to all these features, our chamber delivers top performance, reliability and user comfort so that you can get the maximum out of your gun. Precisely made using CNC machines and with H+PTFE surface finish, this hop-up chamber offers the combination of high performance and ease of use.

• For M60s/PKMs by A&K, Cybergun, etc.
• Precise hop-up adjustment – the regulator wheel has 360° setting range.
• The direction of hop-up regulation is visibly marked.
• State-of-the art design of the bucking's lip fit on the inside of the chamber – successfully tested with most of the buckings available on the market.
• Designed for AEG hop-up buckings with standard lip length (e.g. Systema). To adjust the chamber for use with buckings with longer lip length, it's possible to use the enclosed washers – read more on the lip length issues in our article.
• The adjustment of the hop-up chamber's clearance against the gearbox's opening is done with the enclosed O-rings (two sizes).
