Ataman ATAMAN M2R BULLPUP .357

Hello have an ATAMAN M2R BULLPUP in .357. Has been in a case for 4-5 years and has leaked all air out. Tried to fill but air blows out barrel. Even cocked rifle first and used scuba tank with 3000 psi burst with no luck. Anyone know where to get a disassembly diagram or video that will help ? Thank you in advance.
I don't think you can handle this task even with a diagram. It's not easy to service this rifle, you need to disassemble the air cylinder,to change the О-rings and clean the filling valve. for this you need a special tool that only the manufacturer has. In addition, you will never put properly the firing valve back in place! The rifle is no longer in production, spare parts are not available, if something serious happens to the firing valve, throw rifle away. This rifle was made by Russian drunkards, sorry. It's best to get rid of this rifle as is.

Wow.. that’s pretty harsh judgement on the OPs abilities. Do you know him or are you just hoping to discourage him into giving you the “ unfixable “ rifle??

Here’s an exploded view of the rifle version.. should be very similar.

If you still have your manual that came with the rifle from the factory, I believe they show a parts view in them as well.

Hope this helps..

If all else fails , just dive in and take pics as you go..
 
Thank you. I was able to disassemble- very easy to do- and found previous owner drilled transfer port path and valve and valve is trash. I bought it several years ago and did shoot it 2 times but transfer hole in valve being drilled removed the edge where o ring sits. Now to find a valve.
This is the secret, without drilling the port, you will not install the valve in place, on this rifle, the previous owner knew what he was doing. There was no need to drill the valve, only the port needed to be drilled.Now all that remains is to disassemble the air cylinder.Later I will send a picture of the tool, you can make it yourself from a 26 or 27 mm head. I don’t remember exactly.
