The Maple Leaf MR series hop-up rubber is designed to maximize range and accuracy for Tokyo Marui/WE GBB pistols and VSR-based spring-action sniper rifles. This R-hop style hop-up rubber creates a wide and even contact surface for the bullet, significantly improving the strength of the twist and stabilizing the trajectory compared to traditional hop-ups.
50° hardness is the softest version of MR hop rubber and is best suited for low-power airsoft guns such as GBB pistols and VSR sniper rifles with lighter springs. The softer rubber provides excellent grip on the bullet and also works well in cold conditions.
The MR series of hop rubbers, like the Super Macaron series, have longer and thicker feed lips, which improve tightness and reduce air leakage. The included metal C-clip increases the rigidity of the feed opening and improves sealing, but its use is not necessary.
For best performance, it is recommended to use a flat or curved hop-up presser or an I-Key for GBB pistols.
The Maple Leaf MR GBB / VSR recoil pad is compatible with GBB/VSR barrels with "open cut/bridgeless" barrels.
