Daystate Daystate TSAR Rebuild

[tnbndr]

I bought a used Daystate TSAR off this forum about two years ago. It is actually a Daystate/Attaman . Gun has been really good but recently developed a good leak. Goes from 250 BAR to 90 BAR overnight.
I never received a manual for this rifle so I don't know how many or where all the o-rings are or sizes.
Does anyone have a manual or know where I could send this to get it taken care of? I prefer to send it out.


TIA

@AirSmithCA - may be able to assist. I used to have a Tsar and AirsmithCA still shoots them.

This manual and owners manual / schematic should help

Lonnie has 3 of these as of last time we spoke & I did some barrels for his. ( Early summer 2024 )

I sent @AirSmithCA a message.

There can't be to much to the rifle. Just start slow and lay things out so they don't get lost or mixed up.

It's usually the wispy 1mm x 7mm Oring on the valve ..mits the Achilles heel of these rifles. I just changed one out on my Ataman earlier this week.

Is that easily accessible?
Where is the best place to buy O-Rings and is there a certain type/style I need for this?

 

[woogie_man]

o-ring store
McMaster Carr
Grainger

There are a few different places to get rings.

Well, it was holding air long enough to shoot a match. NOT anymore. It leaks out as fast as it goes in. Out the barrel or breech if I open the bolt ..

Possibly the valve has a leak or is not closing. Have you opened the rifle up yet to look?

I have not opened it up yet. I am a newby to air rifles and worried I may lose or wreck something, but I'm going to have to do something here soon.

Go slow...not much to break on them

Just to put closure to this post. AirSmithCA, aka Lonnie contacted me via PM. I ended up sending him the breech and air tube and he dispatched the leak promptly. He tested and chrono'd it and it is back in my hands and holding air.
I appreciate everyone's input and help in this matter.
