It’s a device that eliminates hammer bounce and thus saves a lot of wasted air. Hammers are spring loaded weights that fly forward and hit the valve pin which releases a blast of air to push the pellet. However the valve with all the air volume of the main tank behind it also acts like a spring and pushes the hammer back but then the hammer spring throws it back at the valve again. This happens a few times every shot wasting air in the process. It’s an issue with guns with such a simple design. There are different solutions out there that try to stop this. The SSG is the latest. I forget what it stands for.
None of this tuning and after market stuff is anything you need to worry about now. Just showing what’s possible if you should like to tinker.
