- 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.
