Mp5 compression problems

newbie Posts: 51 Join date: 2008-10-05

When I got the MP5 mentioned in the earlier posts to shoot bb's It only pushes out some, some times the bb's just roll out of the barrel and most of the time it just dryfires. Could this be from bad compression and if so how can I tell and fix it?

tappet plate, magazine, hopup unit most likely one of those areas is your problem, of course check the hopup and a diffrent mag before you break into the gearbox.

I had the exact same problem w/ my TM M4 two weeks ago. I threw in a new hop up, she works just fine now. So ya i agree, check out your hop up, maybe get a new one if necessary.
