Kraken AAP-01 U-Hop Bucking - 60° (Purple)
STALKER 2-Wing AAP-01 U-Hop Bucking for Kraken AAP-01 Chamber Only
The Stalker AAP-01 U-Hop bucking is designed to fit the AAP-01 and AAP-01C models and is specially designed to work the best with the Stock Nozzle and CowCow Nozzle and at the same time also allows your blowback unit to close completely unlike other buckings that you try to fit with the CowCow nozzle. This non closing blowback unit problem occurs because the stock nozzle and the CowCow nozzle have different diameters. We have therefore designed a bucking that is perfectly designed for both nozzles and let the blowback unit close completely.
It's important to have the right size of bucking entrance to prevent too much of a sticky nozzle that get stuck in your bucking. If your nozzle is stuck for too long in the bucking while reloading, then it changes the whole cycle movement timing of all reloading parts that will reset your pistol to load and fire another BB. For the best reload timing and feeding of your system, we recommend using this specific AAP-01 Bucking.
The U-Hop has the same internal patch as the famous SR-hop bucking, but the U-hop has a greater maximum adjustment distance and therefore works better with nubs that move vertically on the bucking as in most TDC hopups.
It has its own perfect balanced properties of good material, design, and bucking patch fitment for optimal performance of your BB flight path. We wanted to have the largest bucking lift path possible, so we enlarged the front of the hop patch, as you see in the product photos. This Shape is a U-Shape and that's why we call this rubber a U-Hop rubber.
We are very grateful to the people who tested this product, and we hope the community will enjoy it as much as we do!
