When you use more powerful, overfilled gas ram, you damage your airgun and optics. Often airgun with overfilled gas rams shoots weaker (It sounds unreal but happens). Our gas ram's force is OPTIMAL = MAXIMUM for this airgun.
Advantages of gas ram
s:
1. Long lifetime
2. Airgun may be cocked for a long time and it is not harmful for gas ram
3. Strict direction of compression
4. No clang, no vibration - soft recoil
5. Shot is more quiet than with standart spring
Attention! Please specify the model of Your rifle. For the 125 model offers a seal with a diameter of 29 mm. For 135,150,155 models offered seal with a diameter of 30 mm. If You have not specified the model gas ram is equipped with a seal 29 mm.
