AGN'ers!
Good day.
I have inherited a Marksman 0035, break barrel, .177 caliber rifle. I have searched exhaustively for a disassembly instruction video, or information on disassembly, yet cannot find any for this rifle specifically (none on AGN either). There are SOME that look similar, but are not exact, so I'm a little hesitant to start tearing into it with the high-pressure springs inside.
The rifle will not blow any air through the barrel or at the breech seal, so I assume that there is a seal internally somewhere.
Knowing that this is an older rifle and not an expensive one, perhaps it's of no value to try and fix?
Might I be better off selling for parts?
It is in really great shape, almost looks brand new, but I can tell that it has been fired at least a little.
Any of you valued input is appreciated.
Thank you!
Mike
 
Probably pretty straightforward. Take the stock off and take some pictures to share. Probably a vertical lug that gets turned out followed by one or two cross pins that hold the end cap/ trigger housing in. If you punch them out and then hold downward pressure on the end cap on the floor while you remove the punch it should pop apart pretty easily. If there is a safety hanging off the back a block of wood may come in handy. Just a guess though. Pics would help.

I think that's a Norica GT600 or a GT700. You probably need to make a tool to reach past the trigger group and depress the spring. I made one for another Norica model that might work but I don't like to loan things because people in general don't seem to know how to return things promptly.
This might be helpful https://www.pyramydair.com/blog/2010/12/beeman-gt600-air-rifle-part-2/

A Norica Jet and the tool I made. Push the spring in and then you can get the trigger assembly out. Followed by the spring and piston.
Your gun’s probably a different model

Yes, I read the GTA information last night, but it wasn't as clear as I thought it would be.
The diagram is very helpful, too bad it doesn't have what the part numbers are though.
Thank you for both items!
I'm assuming that perhaps JG Airguns has some parts? I'm also assuming that they should understand which parts I need? Anyone dealt with them at all?

The original seal goes crumbly and nasty and hard to get cleaned out of the cylinder. Similar to a few other guns, we know about. If you replace the spring from custom air seals and get the seal from me, you won’t be out much coin.
Find a custom air seals listing on eBay. Click on “sellers other items”. Look through the springs they have available. Read each item description carefully. They are actually very good at their application descriptions.
