The Maple Leaf VFC & GHK M4 / AR GBB CNC aluminum hop-up unit offers improved accuracy and efficiency for GHK M4 and VFC M4 GBB-compatible airsoft gas rifles. The part is made from aluminum using precision CNC machining. The unit is designed to work seamlessly with Maple Leaf GBB and Crazy Jet-spec precision barrels. It features a “Dual adjustable system” hop-up adjustment, allowing you to adjust the hop-up in the same way as the original design through the cutout in the outer barrel without tools, or alternatively by turning an M2 adjustment screw with a suitable key.
Maple Leaf recommends using Super or Wonder series GBB buckings with this hop-up unit, as they fit directly without modification. Other GBB-compatible hop-up buckings require cutting off the alignment ridge on the side of the bucking before installing it into the hop-up unit!
