There are two adjustments you can do to the kit to assure it fits perfectly in your rifle
In order to get your kit working optimally, you should adjust the valve. There should be 1mm distance between the striker (in retracted position) and the valve button.
Unscrew to separate the kit
Open it up
Hold the valve button a and rotate the other end with an hex key to adjust.
Put it back together
Finally screw it back.
To assure proper feeding, you can do the following:
Unscrew to free up the feeding tube
Adjust to the desired lenght
Screw it back together
