NOTES FROM LUKE: This precut Adventure Force Sentry X2 spring is cut from a K26 and has been tested to match your blaster. With an increase in about 40+FPS from the stock average of 90FPS, this spring is the perfect simple mod for more power and accuracy. This spring has been custom cut and tested to fit the Adventure Force Sentry X2 blaster.
Installation is pretty easy on this one, however you'll need some extra force to compress the spring to get it back through the whole in the opening of the plunger tube. Make sure the orientation is right before trying to put it back in. You can lose the trigger lock pieces if you want. The prime on this is pretty strong after you've got everything put together so this mod is recommended only for adults.
