The Jing Gong G36 butt locking pin is a metal mounting pin that is intended for attaching the butt of G36 series airsoft guns to the frame. The pin is made of durable steel.
This spare part is compatible with most G36 series electric guns, including Jing Gong, Tokyo Marui and Classic Army models. In some cases, it may be necessary to fine-tune the pin or frame shape, especially if the gun is not manufactured by Jing Gong.
