This hop-up bucking set by Madbull features 60 degree rubber that is softer than 80 to 90 degree rubber found on standard bucking. This easy-to-install accelerator 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. This Madbull accelerator set comes with two sets of bucking and spacers.
