It does work.. BUT and its a big but JG Bar 10 internals are weak as it is with the stock spring it comes with so more power is just going to destroy things inside it stick with what you have at the moment its like 400FPS stock isnt it? Im pretty sure thats good enough. Buy a spring guide / sears etc so your rifle can take the power.
I was told if i want a 130SP spring for my TM VSR G-Spec which is about 350+ FPS with 0.20's that i would need a spring guide for that and thats in a TM which are known for their great internals.
