310 fps is just fine for outdoors
If your AK is even compatible with marui parts, just buy an 8$ guarder clear hopup rubber, start using .25g BBs and you'll double your range and accuracy.
But that's the only real upgrade you should do to that AK, unless you have a metal gearbox i HIGHLY recommend not upgrading anything in the mechbox.
Tamiya connectors suck.
