Maple Leaf I-Key Hop Up Tool - Tokyo Marui and WE GBB

Maple Leaf I-Key Hop Up tool for WE and Tokyo Marui style gas airsoft guns. An adjustment tool for your pistol's hop up unit. Adds extra pressure and tension on all WE, TM, and WE compatible gas guns. This allows for use of heavier BBs such as .28g, .30g, and higher. Shoots excellent with .30g! Slightly curved and perfectly paired with Maple Leaf hop up buckings. Key is silver color - not red in the picture (it's the exact same thing). You will get a silver one.
