I recently had just bought a Well MB06 and as soon a I pulled it out of the box I found out that there was a problem. When I contacted the website I had bought it from and finally had got the Return shipping information I was told I would have to pay $20 in shipping fees just to send it back.With that in mind I just said I will just fix it myself. And now I can't figure out how to fix it. The main problem is that the bolt won't pull back, though it does move up and down. And the trigger system is a little screwy, possible related to the bolt problem. I what to see if someone can give some advice on how to fix it otherwise I'm going to have to sell it for parts.
No the bolt does not move any bit backwards. When I first took it apart I when all the way to the bolt assembly and stopped because I got stuck there and When I pulled out the trigger assembly I notice that when I pulled the trigger I was getting no response from the other parts in the trigger assembly
I finally got to working on my gun but I can't figure out how to remove the bolt assembly. I tried looking on Youtube found two disassembly videos but they both have little to no value in getting my problem fixed. i've gotten it all the way down to bare but since the bolt isn't moving back I haven't been able to remove the cylinder.
After giving the gun the time of day I finally was able to figure out what was wrong. After removing the cylinder and checking it's functionality it seem completely fine. Then moving along I reinspected the trigger box I noticed that one of the pieces seem to stick. It turned out one of the springs on the inside was installed wrong resulting in the cylinder being jammed.
