IMPORTANT: The valve is sealed by high pressure, it won't leak when the pressure up to 3~4MPa.
1.We also have Shoulder Stock, you can find it from our store
2.We have set the best pressure before shipping, so you'd better not adjust or disassemble them at will.
3.To install them, you only need to keep the original barrel, grip & trigger set, and Probe.
4.We will make high pressure and sealing test before shipping, so there may be some sign of use.
5.In the case of keeping best initial velocity, it can be shot about more than 20~50 times.(Due to pressure setting and length of cylinder).
