MR. HOP is a hop-up bucking made of a mixture of silicone, designed for the VSR & GBB series replicas.
This material tolerates low temperatures very well, without the Cold-Bore Shot effect – it does not require “warming up” to obtain a stable flight path and full range.
Works great in sniper rifles.
Thanks to the larger and wider surface of contackt with bb provides optimal spin – ideal for heavy balls.
Before buying, make sure that the hop-up rubber will fit your barrel.
