As with the Merc II Sniper Rifle and the Tag Master Pistol, the main part of this mod is removing the underslung missile launcher. I covered the void left in the bottom with a piece of masonite and a small piece of wood. To attach I put screws into the bottom of the tagger about an inch from the front and then two into the front of the trigger housing. I then took the orange tube the missile fits around and cut off about an inch of the front and glued it into a 1" hole I drilled into the the big circle at the front of the tagger. This, once you cut off the fins allows you to use the missile as a hand grenade, you simply press it onto the tip, wait for the "rocket ready" and then heave it. The final part was the drone grip (optional) just slice it off right above the battery pack holder and bolt it to the bottom"
