Maple Leaf Wonder GBB / VSR Hop Up Bucking - 50

Maple Leaf Wonder hop-up rubber is designed to improve long-range accuracy and bullet stability. This 50-degree hardness version is best suited for low-power weapons (under 110 m/s / approx. 1.2 J). The W-shaped internal contact surface allows for a strong and controlled backspin, which improves range and accuracy, especially when using heavier bullets.

The rubber's external sealing rings improve air tightness and prevent the rubber from moving around in the hopper unit. The Wonder rubber has no ridge, making it directly compatible with VFC/Umarex gas rifles without additional adjustment.

Aptitude:

– GBB gas pistols: WE, Tokyo Marui, KJ Works, VFC (Umarex)

– GBB gas rifles: e.g. VFC/Umarex M4 GBBR

– VSR-10 spring-action sniper rifles and similar (VSR standard)
