Re: madbull shark hop up rubber

wellt eh point of them is to stop double feeding, but in some aegs the can change the velocity

as far i am aware the back is for voer 470fps, its a very stiff rubber, the silcon one is much softer and tears easyly but its supposed to be better than the black, the red is a softer rubber than the black and silcon (60 degree if im not mistaken) and also comes with the fins to stop the double feeding just as the black and silcon and the blue is isnt a accelerator, its just 60 degree rubber and doesnt have the fin bucking

it all depends on the setup of the gun, barrel etc
