If the piston in your Airsoft weapon is leaking, your gun may work, but it wont fire consistently. The best way to solve this problem is to replace the O-rings with this high-quality PolarStar F2 HPA set.
These small rubber rings are placed at the tip of your piston, preventing the air from escaping when pulling the trigger. This helps ensure consistent shooting, allowing you to prevail over your enemies.
The set is constructed from remarkable rubber for a long lifespan.
