Just picked up a free JG Bar-10 from a guy on craigslist. The gun is basically brand new it's just that it slam fires. And I am not too familiar with the VSR/Bar-10 series, so I was wondering if someone could help and tell me how to fix this or what the actual problem is.

Could be any of the following:

1. Cylinder guide rings are worn/missing resulting in the wobble of the cylinder unit causing the sear not to be able to catch the piston.

2. Worn sears (most common problem)

3. Broken sears (perhaps it snapped or something)

4. Piston is worn down
