More info

The Hop-up chamber uses a new and innovative system for extremely precise adjustment of pressure placed upon the hop-up bucking .

Driving or loosing screw, hop up lever will be up and down by smart mechanical pressure. Smart mechanical pressure can avoid o-ring failure which results in a leak.

The Action Army CNC Aluminum Hop-Up Chamber uses a new tension system to apply pressure to the fired BB, this makes the trajectory of the BB is much more consistent after every shot over the original hop up chamber. This tension system is controlled by a screw that goes through the bottom of the hop up chamber with the magazine removed, rather than the top and maintains tension much more efficiently than the stock unit. The metal construction provides a much more durable unit than the stock plastic one.

Upgrade your stock chamber with this CNC machined unit. Fits Tokyo Marui VSR-10 sniper rifles, Echo 1 PSR, clone guns, JG BAR-10, etc. This chamber is a great compliment to the Wolverine BOLT system too!  The Action Army Hopup Chamber is a must-have for VSR sniper rifle users. Its easy installation and simple operation is a breeze compared to the PDI system. Highly recommended for custom rifles!
