Description: The ProWin AK CNC Hop Up Chamber is a great upgrade from your AEG's stock plastic, or weak cast metal hop up chamber. Metal hop up chambers are known for providing a better air seal against the AEG's gearbox, and feeding much more smoothly than plastic chambers. Many cast metal hop up chambers, however, have weak areas in the metal from the casting process, but this problem is completely eliminated with the ProWin chamber. This hop up chamber is machined completely out of aircraft grade aluminum, meaning it is both lightweight and durable, and the bright blue color helps give your AEG a custom look. Specifications: Manufacturer: ProWin Model: AK CNC Hop Up Chamber Color: Blue Size: Fits Marui-style AK AEG Package Includes: One (1) hop up chamber Features: CNC Aluminum Construction Blue Anodized Finish Increased Stability Improved Air Seal / Accuracy Please Note: Professional installation is recommended. Improper use or installation of upgrade parts are 99% of the time the cause of failures of these items. Please thoroughly inspect any parts for defects before attempting installation. Due to the high possibility of damage from improper installation, we will not warranty parts after attempting installation.
