There's no way the FPS should be that low, even with a stock barrel. You need to look for air leakage.
Check the o-rings around the piston head and cylinder head, and see if the o-ring is still inside the nozzle. Check the hopup rubber and make sure it's sealing against the barrel and not leaking air.
Are you testing for FPS with the hopup on or off?
If you can't find any air leaks, I'd check the spring in another gun - if the FPS is also low, it's the spring. After confirming there's no air leaks or a weak spring, I'd then start looking at the barrel.
