Is it the button or the light? If you dont know, just take the gear box out then press the button (when you take it out all you will see is a yellow button). If it turns on then something is wrong with the button piece (is separate from the gear box, but what you see on the outside). To be honest though it should be obvious if the actual button piece is broken, its just plastic. If it doesnt, you probably have stealth mode on, I doubt the LED on it is already dead.
Why do people do this wanna-be hk thing? I mean hk people dont even play paintball, they just whine and start drama while wearing the ugliest stuff. Seriously you find light blue and pink to be attractive colors for your parents 1500 dollar investment (your gun/marker)? If you want to whine keep it off the field and save it for the internet; O wait! THATS EXACTLY WHAT YOU DO! Haha, if you don't play then don't whine.
I want your G6r parts and upgrades, sell them to me, because you wont get anything for them if you sell/trade them with the gun.
