Maple Leaf F-Key for WE GBB Pistol

The Maple Leaf F key is made from machined aluminium and is designed to fit under the hop lever arm to give even pressure producing more consistent accuracy.  

Please note that the F Key is to be used on the new WE pistols and those that have had the hop arm changed to the narrower version. If you have the older wider (Marui) style hop arm then choose the Maple Leaf I key instead.
