AEG Hop up Unit, Bucking, & Accessories

Increase Range and Accuracy!

Featured here are hop up units, and hop up buckings. Buckings are an important part of ensuring maximum range and accuracy by providing consistent backspin to the BB as it exits the barrel. Upgraded hop up units not only increase compression, but also help the bucking and inner barrel from minute wobble. Minor wobble at the base of a shot will result in a large margin of error further down the BB trajectory. Both the hop up unit and the bucking must be upgraded to result in maximum accuracy.
