Maple Leaf F-KEY Hop-up Tensioner for TM / WE GBB Pistol

Maple Leaf F-Key hop-up (spacer) made of aluminum for GBB pistols. The F-KEY is installed between the hop-up lever and the hop-up rubber. It is designed to provide more even pressure on the hop-up rubber, thus improving accuracy and bullet range.

The Maple Leaf F-KEY is compatible with newer WE pistols that have had the recoil adjustment lever replaced with a narrower version. If your gun has an older, wider (Marui) style recoil adjustment lever, choose the Maple Leaf I-KEY recoil depressor.
