PRODUCT DESCRIPTION: This precut BuzzBee Sentinel spring is cut from a K26 and has been tested to match your blaster. With an increase in about 25+FPS from the stock average of 75FPS, this spring is the perfect simple mod for more power and accuracy. This spring has been custom cut and tested to fit the BuzzBee AirWarriors Ultra-Tek Sentinel blaster.
On installation we found it easier to access the plunger from the back end by carefully unscrewing and removing the catch mechanism. You shouldn't need to take any other parts out, then just go ahead and slide your new custom spring on. Another side note is you'll need to remove the blue plastic cover over the magazine opening in order to access the last two screws for removing the shell.
