Airsoft Whizzbanger 40mm

This is just an airsoft version of the whizzbanger from H3VR, for firing 40mm grenades. 

To assemble your whizzbanger, you will need the following 

• a 5x65mm rod for the firing pin mount 
• another 5mm rod for the firing pin itself (the length of this pin depends on the length of the spring you use for the firing pin. My firing pin was 75mm, but yours might be longer or shorter than that)
• A spring for the firing pin
• whatever 40mm grenade you desire
• A picatinny foregrip to use as a pistol grip

Assembly:

You're going to want to take your firing pin and glue it into the firing pin cap with some superglue. When it's dry, put your spring over the outside of the firing pin, and slide it down to the end (so it's touching the firing pin cap). Then stick the firing pin through the firing pin mount, and glue the firing pin stopper on the other side, to prevent the firing pin from falling out the back. Then just use the 5x65mm pin to fix the firing pin mount to the main body. You might have to glue that pin in as well.
