Chamber M4A - PRO

The Maxx Model CNC Aluminum M4 Hop-Up Chamber is designed to provide precise adjustments and superior performance in M4-type AEG rifles. Made from CNC-machined aircraft-grade aluminum, this hop-up chamber offers fine tuning via its rotating dial and high consistency in BB trajectory. It is also compatible with a wide range of configurations, including R-Hop, Flat-Hop, and Standard-Hop systems, and is equipped with an innovative BB retention system to prevent shells from falling out when removing the magazine.

Characteristics

• CNC Aircraft Grade Aluminum Construction: Tight tolerances for improved accuracy, consistency and durability.
• Precise adjustment rotary dial: Allows fine adjustments of the hop-up to maximize the accuracy of each shot.
• R-Hop, Flat-Hop and Standard-Hop support: Keeps BBs shooting accurately and consistently with different hop-up settings.
• Double O-ring design: It offers superior air sealing, preventing FPS loss and ensuring optimal performance.
• BB retention system: Prevents BBs from falling out when removing the magazine, ensuring greater efficiency during the game.
