Hey this is my Knex Grenade Launching Turret, to fire you would pull the handle which would make the grenade go flying. I designed the grenade so it explodes ON IMPACT, which was hard to make but it worked out. It has a good range and is fun to blow stuff up with it. This is a prototype so dont be very harsh but it works very well. It also doesnt jam, it is highly accurate, has cool iron sights and it can rotate on its octo-stand 360 degrees. Dont forget to rate!
