​Sonic's Turret Pistol




About: I like to make things and invent new products. i also like to cook read books and play with KNEX LEGO and other things. My other main interest is companies i like to read about them learn about them and keep...

Sonic's Turret Pistol this is my 2nd entry for the rubber band contest so please vote!

After making some different Knex turret guns I thought that it might be fun to make a turret pistol so here is my first turret gun. It uses a TR8 like turret, with some small changes. It has no ratchet mech, I did not quite know how to make a ratchet, but you don't have to hand turn it to the next round.

Also I tried to take some better pictures. Tell me what you think!

This gun gets pretty good range. I don't have a room big enough to do any long range testing but I will post the stats when I do some more testing.


true trigger

hold lots of bands

low piece count

no broken parts

looks nice IMO

pretty compact

easy to make, good gun for beginners

comfortable handle if you hold it with a good grip


no ratchet mech

hurts a little if you hold it to loose

Please give me your feedback and thoughts and also please comment, like, and subscribe.

    That might be cool for a profile picture but it seems like a waste of time i think i will work on my rail action rifle instead.

    Well let's face it using the holes in the connectors to guide the ram rod is a older technique that is not used very often anymore. But I do realize it's kind of hard to implant a 5 layer structure to guide the ram on a turrent gun.

    I see your point, but it's the same system that KILLERK's TR uses. If you want a loose assembly fit around the firing pin then connector holes are the best things to use. These make up a straight, consistent path for the firing pin to travel along, for optimum acceleration. It's convenient to use this on a turret gun because there is no need for access to the sides of the barrel, like on a magazine fed gun, so all you need is for the firing pin to accelerate and strike the turret pin. This sort of barrel is also stronger along its length, allowing you to stack up rubber bands if you so desire.

    If you had a design which used a magazine for reloading, then a barrel with a rectangular section would be needed. Along its length, the barrel is less consistent and prone to friction, misdirection and blockage. With sufficient pin stabilisation this design is more than good enough. However, since the TR aside from the turret is little more than a well engineered tube-and-stick gun, I think that you're better off using a connector hole barrel IMO.

    I see what your saying I just prefer a 5 layer gun myself. I guess when I say 5 layers is modern, it's because I belive right now is kind of the looks area but in a year or so people are going to get tired of a regular ram rod hitting a bullet out of a mag and move back to the innovative stage. I guess I'm starting to get a little off topic so I guess every one has there own opinion so I can respect that.

    Yeah but this is my first turret gun so i was thinking that maybe my next turret pistol will be slide action or something a little more advanced i just need to get some more parts.

    Looks pretty good! I would say regarding Lucas's comment that it really hard not to make a turret based gun look dated because the body is really hard to integrate into the modern five layer Knex gun. Overall I think you did a great job making the turret fit in the body you wanted it in!

    I did not mean to sound like I did not like it, I just personally think that it looks outdated. I would love to see someone build a turrent gun that looks nice and modern. I am horrible with anything that involves a turrent so I'm not at all saying you did bad I just want to see something newish.

    Yeah, turrets are hard to make in the five layer body style. Its especially hard to implement the turret toward the middle, which would help balance the appearance in my opinion.
