Silicone MR. Hop Up Rubber 50° for VSR/GBB [Maple Leaf]

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..
