Knex Mag-fed Grenade Launcher

Hello everyone! I really didn't contribute to the 'ibles community,so I thought I would make my first gun. So I present you the knex mag-fed, bolt action grenade launcher. Stock and parts of handgrip is from Dr. Richtofen.
Pros
- 5 round gravity-fed magazine
- good range depending on rubber bands. I got up to 60 feet.
- fast rof for grenade launcher
- ammo actually explodes on landing,making it an actual grenade
Cons
- stock part is flimsy
- not the best trigger

So should I make instructions for this? Please leave comments below. Thank you
