Hop Up Chamber Prometheus Elite CNC - M4/M16

This Prometheus Elite CNC – M4/M16 hop up chamber is CNC machined out of impact-resistant aluminium. It’s very lightweight and it’s produced with minimal tolerances, so you can be assured it will fit the replica perfectly. This hop up chamber was designed specifically for the M4 and M16 airsoft replicas.

The Prometheus Elite CNC – M4/M16 hop up chamber comes with the following two buckings:
• Prometheus Original Purple – provides a good air seal, which positively affects the replica’s reach and accuracy.
• New 60 Degree Blue – offers ideal friction distribution for replicas that shoot between 350 and 400 FPS.
Both buckings fit the inner barrel on the M4 & M16 airsoft replicas perfectly.

There’s a large adjustment wheel on the Prometheus Elite CNC – M4/M16 hop up chamber, that uses a ball bearing to produce clearly audible clicks. It also enables extremely accurate adjustments and it prevents the adjustment wheel from shifting to a different setting. The hop up chamber features a so-called vertical hop arm. This means there’s a small plate placed below the hop arm. The hop arm works as you would expect; turning the adjustment wheel allows you to set how far the nub is pushed into the bucking. However, the plate below the hop arm -kept straight by two slots on both sides of the housing- ensures the pressure is evenly spread across the nub and the bucking.
