Maximize your rifle's full potential with this next-level TE Pro hop-up chamber from Maxx Model. Constructed from precision CNC aluminum, this AEG upgrade is reliable in the most powerful of airsoft guns, and can withstand the hard lifestyle of airsoft warfare. The universal design of this hop-up chamber allows it to be used as an upgrade in all AEG buckings and M4 style air nozzles, and is specifically designed for fast feeding BBs and to prevent dropping excess BBs when removing the magazine on M4/M16 style rifles. The Latching system will close when the magazine is removed, and opened again automatically once the magazine is inserted back into the rifle. Two vinyl covers on either side of the hop-up housing prevents dust build-up within the chamber, and allows players to view the BBs that are still left in the hop-up chamber. An integrated dial knob allows players to make precision adjustments while the specially designed hop-up arms constantly fire BBs straight and accurately with every trigger pull. It’s important to make sure your hop-up chamber is perfectly centered, straight, and air tight; and for that Maxx has installed 3 high quality O-rings and 3 compression springs on top, bottom, and in the center of the housing. The TE Pro hop-up chamber is designed to accept a wide range of air seal nozzle lengths ranging from 20.50mm to 21.00mm, and is compatible with most aftermarket soft and hard rubber buckings commonly used in AEG upgrades. For added convenience when making adjustments or maintenance, the brass threaded slot pin is completely removable allowing players to access the inner parts. Ensure your rifle shoots straight and far despite all weather and battle conditions, thanks to this hop-up chamber upgrade from Maxx Model.
