I have owned a Well MB02 for a long time, and decided to upgrade it. I bought a new sear set, and upgrade kit for about 80 bucks in total. The piston and spring guide did not fit the cylinder, so I sanded them down to the diameter of the stock parts.
With all these parts installed, I test fired only to have the bolt be locked back. I have tried using the old spring guide. It works for 5 shots then locks the cylinder forward and does not allow the gun to fire. I now realize that the MB02 and all Well VSR-10 models are terrible.
The piston and spring guide are sanded to a diameter of 20.95mm. I am just wondering if these would work in say a JG BAR-10. Or would I need to buy new parts? I am also considering selling these parts if possible, and just up and buying a A&K SR-25. All in all I just ask should I stick with the MB02 and try to make it work? Should I start over with a BAR-10? Should I just ditch the VSRs? And if I do get a BAR-10, will my sanded parts work? I am just curious to see what the typical piston diameter is as well. Thanks guys.

The spring guide will probably work although the piston could cause issues. I don't think it will though, but it should fit a BAR 10. WELL VSR's are the same as real VSR's, the only difference is the smaller cylinder diameter, hence you had to sand things down.

If the bolt is locked back then you have a problem with your cylinder, not with the spring guide or piston since those can move inside the cylinder anyway. If it's locked forward, same story. You probably have something else jammed. I can't say what though with so little information.

Do I need anything else in order to upgrade a BAR-10? Do you think these parts will really work in the gun? If you wouldn't mind could you measure the diameter of your piston by any chance? I'm actually thinking about just getting an Sr-25 instead.

bar-10 will be great choose. More simple than sr-25
