MAXX Hopup Chamber M4P

The integrated latching system is designed to prevent BBs from falling out of the chamber when you remove your magazine. This eliminates the common issue of having loose BBs spill into your receiver or drop on the ground during reloads.

Yes, the M4P PRO is engineered to work with both R-Hop and standard hopup buckings. This versatility makes it a great choice if you are experimenting with different accuracy-enhancing modifications.

The chamber includes an interchangeable inlet adaptor specifically designed to ensure proper alignment with HPA nozzles. You should verify that your specific HPA engine nozzle is compatible with the 11mm outer diameter of the adaptor for a perfect seal.

The Delrin C-Clip provides a secure, wobble-free connection between your inner barrel and the hopup unit. By eliminating barrel movement, it ensures consistent air seal and shot-to-shot accuracy, which is critical for high-performance builds.

While this unit is optimized for HPA engines due to the inlet adaptor design, it is built to fit standard M4/M16 style AEG receivers. However, you should check your specific receiver's dimensions against the 51.15mm length and 37.75mm height to ensure a drop-in fit.
