In addition, the cylinder head is supplied with 2 pads, which reduces the sound of contact between the cylinder and the hopup unit. Which makes your TAC41 just a little quieter.\u003c\/p\u003e\n\u003cp\u003eThe design of the Kraken TAC41 hopup unit makes it impossible to misalign the hopup between the hopup unit and the bucking\/outer barrel. The hopup unit has 2 cutouts that work perfectly with the Stalker TAC41 Double Fin SR hop buckings. The complete hopup avoids wobbling with the square barrel spacer and 2 locking screws. The main body of the hopup has a raised lip under the wheel to prevent water from entering the TDP nub compartment.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eInstallation instructions\/requirements:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eYou must have a GBB style barrel to install the Stalker Kraken TAC-41 TDC hopup unit, which can be any length you require.\u003cbr\u003eAlways make sure you don't have to force your bolt kit forward, if your bolt kit cant be pushed down into your lug socket, you didn't grind the bolt kit screw enough'(check video), your cylinderhead is not closed on the cylinder, or your cylinder head front rubbers are not installed deep enough.\u003c\/p\u003e\n\u003col\u003e\n\u003cli\u003eDisassemble your TAC-41 as described in the Silverback manual.\u003c\/li\u003e\n\u003cli\u003eUnpack your Stalker TAC-41 TDC hopup unit.\u003c\/li\u003e\n\u003cli\u003eInstall the stock Silverback ball plunger clicker pin to get wheel clicks or you can choose to leave this clicker ball out and install one supplied little O-ring onto the hopup wheel portion of the main body (small O-ring).\u003c\/li\u003e\n\u003cli\u003eInstall the Stalker TAC41 Double Fin SR-hop Bucking on your GBB barrel.\u003c\/li\u003e\n\u003cli\u003eSlide the main body of the hopup unit over your bucking.\u003c\/li\u003e\n\u003cli\u003eSlide the square spacer over the inner barrel with the arrow pointing to the end of your inner barrel in the hopup.\u003c\/li\u003e\n\u003cli\u003eInstall the screws through the main body of the hopup unit and through the barrel spacer to lock everything in place.
