I had 0 problems with the stock internals on the VFC man. The only thing I changed out was the plastic hop up to a modify metal one. Other than that I ran it stock at 380 fps and put 30k rounds through it before the contacts shit out on me.

Run the internals until the go. You don't need to replace anything in the gun before it does. Even the piston lasted a full season of gaming before I had to replace it.
