I bought an AIM M4 off my buddy after he has problems with it. In stock form the motor and battery heated up before the battery died after a few shots. Believing it might have been something wrong with the motor, I replaced it with a Classic Army. To my dismay this didn't clear the problem. After doin plenty of research on which route to go I bought every part to completely replace everything inside. I chose to go with an Airsoft Surgeon Stage 3 spring with Guarder torque up gears. According to all the spring charts the spring is rated around 463fps. When it was chrono'd at the shop is only shot like 386fps. I'm using a 10.8v battery so it has plenty of power. The only thing I hadn't upgraded was the barrel but this shouldn't have that much impact would it ?
