The original Marui VSR-10 arm lever is made of plastic. When using heavier BBs, it often fails to provide sufficient spin and may flex slightly between shots, causing inaccuracy.
The aluminum arm lever with a U-shaped nub ensures even pressure on the hop-up rubber with an extended contact surface. This provides the BB with a more stable and stronger hop-up effect.
Note:
- Due to the curved extended nub, the U-shaped arm lever is only compatible with barrels that have an open hop-up window (see image). If your barrel is not compatible with the arm lever, the bridge covering the hop-up window can be removed at your own risk.
- This arm lever works best with Maple Leaf hop-up rubbers that feature an extended hop-up mound.
- Compatible only with Tokyo Marui VSR-10 and JG-BAR10 series.
