Maxx M4E CNC Aluminum Rotary Hop Up Chamber for V2 M4 AEG

The Maxx Model Products M4E Hop Up Chamber for standard M4 AEGs is the newest model for 2024. The M4E is essentially a revised and updated version of the M4A. Some key features are the reworked internal tolerances, pivot pin with o-ring retention, included barrel shim o-rings, inlet adapter shims, and other minor dimensional tweaks to improve reliability and performance. We've found this unit to be a welcomed upgrade over the older M4A as this has better compatibility with different buckings and barrel combinations. Please note that the BB retention system is optional. Removing this feature can help with feeding in certain cases where magazine fitment is sub optimal.
