Description

This hop-up rubber offers consistent hop,  thanks to the unique large patch & 60° hardness. It’s great for 0.25g Bbs to 0.32g BBs.
It handles cold temperatures as well as hot, it is a perfect year-round hop-up rubber.

 Make sure there is no silicon/oil on the bucking and regularly clean your barrels for best performance.

 This bucking has a bottom indexing rib and a large contact patch. It is meant to be used with the premium 6.01 steel inner barrel. Some stock barrels may not be compatible (e.g., SSR77, SSR63, SSR90), and some hop-up chambers might need modifications.
