Install Service for Xbox 360 Halo 2 Double Shot

***This is a service, you are NOT buying a controller, just the service to install this mod in one or more of your controllers.*** Since this is a service Shopify doesn't give me a shipping address, thus this will be shipped to your billing address. Your controller must be an Official Microsoft Wireless Xbox 360 CG or CG2 controller.I have a limited number of these on hand.  Here's how it works, buy this after you pay I'll send you my shipping address, when I receive your controller I will mod it and get it back into the mail, usually within three business days, as these take a lot of time to install. Price for this install service:Halo 2 Double Shot Mod Kit, installed $43USPS Ground Advantage return shipping $7 Controllers are returned in a box. This mod has 5 modes, 2 for the right side button and 3 for the left side button. The right side button can be either Double shot or Rapid fire. The left side button Can be BXRR, BYYRR or Quick reload. To change the mode of a button you just need to hold the controllers back button and then press the button on the back that you would like the change.Example: The left button is BXRR but default. If you wanted to change this button to it’s second function you would hold the controllers back button and then press the left side button that you installed. Then release both the back and left side buttons. The button will now function as BYYRR. Follow the same procedure to change it to quick reload, then one more time to go back to BXRR.If you have any questions, Please Ask
