Maple Leaf HopUp bucking for VSR sniper rifles and GBB guns. Slightly narrow entrance for better sealing to achieve more consistent power output. Special pressure point geometry reduces inconsistency between shots for a more predictable trajectory and longer distances. C-Clip to enhance lip stiffness for further sealing, but not necessary to use. Depends on user needs.
Bucking is suitable for Marui / KJ GBB Pistols and VSR-10 compatible air cocking rifles. Super bucking works best with heavyweight BBs (0.40g+)
