About to buy a kwa vm4 t6.
I've read that it is a great gun out of the box other than the hop rubber, although apparently it can be alright after putting a mag of bb's through it.
Thinking of changing the following,
Dropping in a gate titan advance, new gears, new trigger, new hop rubber, new piston and piston head.
1) is it worth it on this gun
2) is it worth changing the hop up, barrel and or spring whilst I've gone this far
Whilst I dont mind spending the money I dont want to change something that is actually worth keeping.
Overall looking for increased rof, fps to be stable at 330/350 for site limits and a good range.
Thanks for any advice
