you will need a new spring and a tight bore for acuracy. for tight bore i recamend PDI

Whats the replicas stock FPS.

hopup bucking, tightbore barrel, new spring maybe. if you get a new spring you will prolly new sears or trigger box, spring guide and piston head. once you start upgrading it can be hard to stop, so be careful you dont want to turn it into a pellet gun

well stock fps is about 300. and i found a spring for it and i have everything else dont really need hopup, and accuracy on it is good i heard so hopefully eveything falls in place. anymore suggestions or links?
