Gas spring setting

All gas springs must be setted by dint of clamp.

Rifle assembly or dismantling without the clamp may cause gas spring failure.

For the gas spring setting you need chronograf and 3mm hex key.

1) Do few shots through the chronograf by the rifle with the gas spring and write down the average speed.

2) Do few shots through the chronograf with the pellet with extended skirt and write down the average speed.

3) Compare the results.

 The speed of the pellet with extended skirt must be lower than the normal pellet about 5m/s or more.

If the speed of the pellet with extended skirt is higher than the normal pellet - you must to output the gas from the gas spring.

 For it:

4) Dismantle the rifle and pull the gas spring out.

5) Twist the screw (just a little bit) of the back side of the gas spring cylinder before the gas outputting and immediately twist it back.

6) put the gas spring in, assembly the rifle and measure the speed again.

 

If necessary repeat the paragraph 4-6 again.

Remember that if the temperature changes a lot the pressure in the gas spring could change too.
