40mm airsoft grenade launcher Kriss Vector style

Here you can watch a little video I have made about the grenade launcher:

Fully functional 40mm grenade launcher, with Picatinny mount.

I spent hundreds of hours on this, to work properly( you can reload the launcher with just one hand in a few seconds, even without looking at it), and look nice, especially attached to a Kriss vector airsoft gun.... :)

I hope you like it, and if you find something wrong, just let me know!

You will need a 40mm airsoft grenade to use it

Please, do not use it with a real gun or against any kind of living thing but other airsoft players or aliens

Printing:

I have printed with PLA plus and 0.24 layer height but can use whatever you want. I recommend using the original orientation of the pieces ( especially for the lock and the Picatinny lock) but you can try different options, it is up to you. If you use cura, the ironing option gives a super nice finish to the grenade launcher. Use support when needed.

Assembly:

I have attached a 7 pages manual, please follow it, it is not complicated.

You will need 2 M3 crews of at least 20mm length and 3 M4x40mm length. The use of glue might be needed just for the rail, but try to avoid it, this way you can open the launcher and replace any part if something breaks.

Use:

Just pull the trigger and enjoy the mayhem :)
