EPeS Hop-up chamber M60 and PKM

EPeS Hop-up Chamber for M60 and PKM introduces a revolutionary design, developed after extensive research, combining high performance with simple control. This version is specifically designed for machine guns A a K M60 (MK43) and PKM with a brick-type gearbox, such as A a K M60 or M249 for PKM.Fine adjustment of hop-up pressure is possible within a range of 360° using the adjustment wheel, marked for easy orientation. The hop-up chamber is equipped with a perfectly tuned shape of internal seating for the hop-up rubber collar, ensuring successful testing with various hop-up rubbers available on the market (EPeS recommends Maple Leaf rubbers).The chamber is made of aerospace aluminum EN AW 7075-T6 with surface treatment H plus PTFE, offering not only high manufacturing quality but also optimal performance.
Additionally, it is possible to secure the chamber against rotation directly in the gun body using the included worm.

Main Advantages of M60 and PKM Chamber:

Designed for machine guns A a K M60 (MK43) and PKM with a brick-type gearbox (A a K M60 or M249 for PKM)
Fine adjustment of hop-up pressure – range of the adjustment wheel 360°
Marked direction of hop-up regulation
Perfectly tuned shape of the internal seating for the hop-up rubber collar – successfully tested with most available hop-up rubbers on the market
Construction of seating for AEG hop rubbers with standard collar length (e.g. Systema), for use with a hop-up rubber with a longer collar, use the included spacer – more about the issue of collar length of the hop-up rubber
Limitation of play of the hop-up chamber in the gearbox hole using the included O-rings of two sizes
Vertically seated pressure of the hop-up rubber – works great with Maple Leaf hop-up rubbers
Groove in the top of the hop-up chamber for the possibility of fixing in the outer barrel assembly
Exchangeable pin for axial locking of the hop-up chamber in the feeder – if necessary, a longer pin (for PKM) can be installed to ensure a perfect fit.
Made of aerospace aluminum EN AW 7075-T6..
