Can A JG M4 Gearbox withstand a madbull m120?
Hi, I own a JG M4 and I realized that it was a pretty bad gun, compared to the other people's gun's I play with. So I decided to upgrade my M4, and change it into an SPR. I bought several things, such as new hop-up, a tightbore barrel, a scope, etc.
But, I also bought a Mad Bull M120 Spring, to upgrade my FPS to around 400. But now that I think of it... Will my M4's gearbox break under the force of the new spring? If so, what can I buy to make my gearbox withstand it?
