MR. HOP is NEW for 2021 and is a hop-up bucking made of a mixture of silicone, designed for the AEG series airsoft rifles.

• Maple Leaf MR hop-up rubber for AEG
• New design "shield" provides maximum hop-up effect
• Ribs on outside help improve air seal with different brands of hop-up units
• Best used with heavy BB's, .28g or heavier
• The rubber has an additional sealing and stabilizing ring on the inside

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.

The barrel on which the rubber will be mounted must have a perimeter cut for this ring. Otherwise, the hop-up rubber will not fit properly to the barrel.
