Kraken U-Hop Bucking - 70° (Yellow)

STALKER KRAKEN U-Hop Bucking AAP-01 for Kraken AAP-01 Chamber (Chamber Only)

The Stalker AAP-01 U-Hop bucking is designed to fit AAP-01 and AAP-01C models, and is specifically created to work optimally with the standard nozzle (Stock Nozzle) and the CowCow nozzle, allowing the blowback unit to fully close, unlike other buckings that you try to adapt with the CowCow nozzle. The issue with the blowback unit not closing occurs because the standard nozzle and the CowCow nozzle have different diameters. That is why we designed a bucking perfectly suited for both, allowing the blowback unit to close completely.

It is important to have the correct bucking inlet size to prevent the nozzle from being too tight, which could cause it to stick inside the bucking. If your nozzle remains stuck in the bucking for too long during reloading, it alters the timing cycle of all the moving parts responsible for reloading, which resets the pistol to chamber and fire another BB. For the best reload timing and feeding performance of your system, we recommend using this specific bucking for the AAP-01.

The U-Hop features the same internal patch as the famous SR-hop bucking, but the U-Hop has a greater maximum adjustment range and therefore works better with nubs that move vertically over the bucking, as in most TDC hop-up systems.

It offers balanced material properties, design, and patch adjustment for optimal performance throughout the BB’s flight path. We wanted to achieve the longest possible lift contact surface, so we extended the front section of the hop patch, as shown in the product photos. This shape is a "U," which is why we call this rubber a "U-Hop" bucking. We are very grateful to the people who tested this product and hope the community enjoys it as much as we do.
