Maple Leaf's CNC-machined Hop-Up unit for the GHK M4 series GBB rifles offers precise and consistent performance. The unit's aluminum construction combines with an easy-to-use dual-adjustment system that allows fine adjustment of the hop-up either from the outer barrel adjustment ring or directly from the hop-up body with an M1.5 Allen key - similar to WE and VFC-style GBBs.
Maple Leaf's 70° Hot Shot hop-up rubber is included, providing a stable back thread and optimal compatibility with Maple Leaf's 6.02mm and Crazy Jet inner barrels. This unit works best with the GHK M4 series GBBs, but is also compatible with some VFC M4 / AR15 GBBs (not with VFC's Variable Hop-Up system).
