Our take: This hop-up bucking set by Madbull features one rubber and one silicone hop-up bucking, which are perfectly suited for nearly all AEG hop-up chambers. This easy-to-install hop-up bucking set includes Madbull's patented Fishbone X hop-up spacers, which provide more surface area contact than normal hop-up nubs. This hop-up set also provides tighter seals and prevents the loss of air compression. Whether you are replacing torn hop-up bucking or upgrading your AEG's inner barrel, this hop-up set is a must have for any airsoft player.
