Maple Leaf MR. Hop Gum

MR. HOP is a hop-up bucking made of a mixture of silicone, designed for the AEG 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 contact with bb provides optimal spin - ideal for heavy balls.
