Here we have it! My knex MS021. (Made up name) 4 pictures of each version. I'm still trying to make an ammo clip to fire yellow rods. Pic 3 is the standard knex barrel. The end of the barrel gets wider. I think the forward grip is not mine. The Butt is better. The ram Doesn't seem to break. It's easy to pull back. I don't know power yet until I get the mag working. Please rate, tell me if I should post instructions on how to build this. Range is about 6feet with a weak rubber band.
