Action Army Company (AAC) was founded on the year 2010 and is currently located in Taiwan. Originally, Action Army Company focused on creating high performance parts for the gearbox but have expanded on creating CNC external parts. Action Army has the ability to CNC machine, die cast, forge, stamp, powder coat, etc. their parts for the most durability and consistent excellent appearance. Their goal is to build new products with a much stronger yet lighter material to achieve the most efficiency from your airsoft gun internally and externally.

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. This Hop Chamber is made for the Elite Force Striker Airsoft Gun.
