Maple Leaf's incredibly durable, metal adjustment key for Tokyo Marui / WE - G17, 18, 19 Hop Up systems.
Fits under the hop arm and evenly distributes pressure to the bucking. Makes your hop up apply more consistently!
Easy to install, simply drop in and align correctly for best results!
The face that sits on the bucking is concave for best bucking patch contact effect!
Used in an upgraded WE G18c, an upgraded Raven EU18c, and an upgraded AAP-01.
Has a noticeable effect on the effective range and grouping of shots, very effective. Little bit fiddly to center on some hop arms which will cause a skewed contact surface inside the barrel. Just keep gentle pressure on the hop arm while it's centered, double check it aligns correctly inside the barrel, and install the hop adjustment wheel to lock it in place.
