PRODUCT INFORMATION

 

CNC Aluminum Hopup Chamber ME Pro (with BB Latching System) unit is precisely made to improve accuracy and ensure consistent air seal for Tokyo Marui (include KRYTAC, except KWA) M4/M16 Standard AEG series. 
The Hopup Chamber ME 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 ME 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 ME 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 V2 gear boxes with 11mm or 11.5mm inner bore. 
More than that, the Hopup Chamber ME 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 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!

Easy to use
Color: black
This dash cam was very easy to install and the video quality is super clear, even at night. I like that it records both the front and inside of the car, which makes me feel safer while driving. The screen is simple to use and the camera works smoothly without issues.

Great camera! Great quality!! Easy to use!!
Color: dark
I purchased this dash cam for added security while driving and when my car is parked, and I’ve been really impressed with how well it works. The video quality is sharp and steady, and it captures way more detail than I expected from such a small camera. Both the front and inside views record clearly, which makes it great for everyday driving. The night recording is one of my favorite features. Even in very low light or complete darkness, the footage comes out clear and easy to see. Faces and surroundings show up well without any harsh glare, which makes a big difference at night. Setup was simple and didn’t take much time at all. It sticks securely to the windshield and hasn’t moved once. The menu is easy to understand. I also like having features like loop recording, impact detection that saves important clips, motion sensing, and parking mode for extra security when the car is off. Overall, this dash cam does exactly what I was hoping for and more. It’s easy to install, reliable day and night, and makes me feel much more comfortable whether I’m on the road or away from my car. I would definitely recommend it to anyone looking for a solid dash cam.
