By mechanically installing, this device converts your Norica spring powered air rifle to the Gas Ram System (GRS), replacing the spring.
The advantages of the innovative GRS system:
* Less vibration: Having no spring vibrations caused by the oscillations produced by the spring to relax once you shoot away.
* Better Load: The absence of a friction spring causes charging more evenly.
* Increased Accuracy: The disappearance of vibrations caused by a traditional spring allows the shooter greater shooting accuracy.
* Constant power shot: Traditional spring systems wear out and fluctuate in power shot depending on how the spring is coiled. The GRS system gives constant power shot (Velocity stays the same on each shot).
* Longer Life: Being a pneumatic system lifetime is superior to that of any spring sytem Rifle upto 6 times longevity.
