Our take: This hop-up bucking set by Madbull features two 60 degree rubber hop-up soft bucking that increase compression, stabilize the BB inside of the hop-up chamber, and improve accuracy. Also included in this hop-up set are two Madbull "H" shaped hop-up spacers. These hop-up spacers are specifically designed to put more consistent backspin on each BB, improving range and accuracy. This easy-to-install hop-up upgrade set prevents multiple BBs from entering the chamber, which can cause two or more to fire within a single shot. This hop-up set also provides tighter seals and prevents the loss of air compression. If you are looking to increase your AEG's compression, range, and accuracy, this simple and inexpensive hop-up upgrade sets is one of the easiest and most effective upgrades you can install on your AEG!
