Maxx Model M4i Pro Hop Up Chamber – ICS M4 AEG Cheap

The newest Maxx M4i Pro HopUp Chamber for ICS airsoft AEGs. The CNC Aluminum Hopup Chamber M4i  Pro (with BB Latching System) silver unit is precisely made to improve accuracy and ensure consistent air seal for all standard ICS M4 & M16  AEG series airsoft guns.  Fits in ICS CXP CS4 EBB M4 AEGs.

**The M4i unit is updated for 2022 and replaced the previous older red ME unit.  The M4i includes more precise improvements including accepting more hopup buckings (Maple Leaf is the best fit according to Maxx) and the highest FPS consistency with any hopup aftermarket chamber.  The ME was prone to more jams, which is eliminated with the new M4i unit.

The Hopup Chamber M4i unit has a precision rotary dial design for fine hopup adjustments, also re-engineered the hopup levers and concave nubs to work best with R-hop, Flat-Hop and Standard-Hop to keep the BBs shooting straight and accurate on every single shot. 

The Hopup Chamber M4i unit is designed to accept the nozzle length from 21.00mm to 21.25mm, and fully compatible with most aftermarket soft and hard rubber bucking without losing FPS or dropping BBs. 
The Hopup Chamber M4i Housing is equipped with a new CNC Delrin Locking C-Clip design to hold barrel tight without wobbling and twisting, and 3 compression springs on top, at bottom and in center of housing to ensure the hopup unit is exactly centered, straight and air tight at all times when adapted to any ICS V2 gear boxes with 12mm inner bore. 
More than that, the Hopup Chamber M4i Pro unit is specially designed with BB Latching System to prevent dropping BBs after removing the magazine. The Latching System can be also manually opened to release BBs from inside hopup chamber by hand. 

***The UV LED Tracer and Electronic Module are optional add-ons (ME Tracer unit) to glow BBs in the dark. Operating Voltage from 7VDC – 15VDC (2-4 cells LiPo, 6-13 cells NiCad). (Sold separately) 

***The Empty Magazine Detection Sensor and Electronic Switch Controller are optional add-ons to stop Motor HPA firing when the magazine is empty. (Sold separately) 

***Test results: FPS might be increased from 10FPS to 30FPS over stock setup. Please check your FPS!
