Indians For Guns

Dear all gurus i am new to this forum. But went through many tropics they were containing valuable knowledge and i loved them reading. What i understood from IFG is that members are like good friends and are always ready for helping each other and also share their personal experience and their knowledge.
This forum helped me quenching my thirst for airgun shoting knowledge in many aspects.
Now one of my friend is using persihole orion sx 100 for 2 years the power of the gun is now low so he wants to change the spring piston seal. So can u respected gurus show a tutorial to change the spring and piston seal.
I am also planning the same AR next week.
It will be very kind act and thanks and wish u happy new year in advance.
Regards
Jay

I do not have orion...
Loss of power may occur for various reasons.
Primary suspects are Piston seal, breech seal and main spring.
You have to inspect all these items very carefully and then infer as to what should be replaced.
In my experience Precihole uses mid powered spring to make the shooting comfortable..
This main spring loses free length with usages.
Best advice is to replace old one with new one.
I learn that Gsmith 27 Diana spring suits well in it but become tight on the synthetic guide.
If one can sand off 0.05 mm of the guide , it regains all its power.
This is information only and not being experimented by me.

Kindly do not use text speak, take the effort of writing in correct english, please write u as you. it doesn't take that much effort. Mod.

Instead of changing the springs, Just replace it with the new nitro piston. It's available here http://www.kovibazaar.com/Springs/Nitro ... 03289.html
