Hop Up Bucking MR. 70 VSR/GBB Maple Leaf

MR. is actually the abbreviation for Maximum Range, the maximum distance you can get from a rifle.
The C-Clip ring from the package has the role of slightly increasing the rigidity of the upper lip to seal better. This component is not necessary for mounting.
The bucking is provided with a larger contact patch, which means that even the heavier bbs will have a hop up effect.
The inner patch has the shape of a "Shield".
The bucking is compatible with sniper rifles made on VSR system and some models of Marui / KJ GBB pistols.
