Works in VSR-10 rifles and WE/Marui/KJW gas guns. The Wonder bucking has a narrow entrance for more accurate shooting styles. Good for heavy weight BBs in the .40g+ range. The Super series buckings from Maple Leaf utilize a concave hop up system and are designed to be used with the Maple Leaf Omega Tensioner. These buckings will fit GBB (WE/TM compatible) and VSR cut barrels (bridgeless).
