I have a CA M16 that has crappy compression and i want to get rid of the problem. My question is can or should i get just a better piston head or do i need the whole piston set? What are the benifits of one over the other? And which brand i should go with? Thanks
just the piston head is fine. Stretch out the o-ring and relubricate it first that should do the trick.

thanks bro. that's what i wanted to know.
If the compression in your gearbox is resolved and you're still not getting the results you expect try working out where the hop unit and gearbox sit together. Some use a stronger spring on the front. Oftentimes a #6 rubber o-ring slipped down the inner barrel to fit against the front of the hop may also do the trick.
