Tr18 Turret





Introduction: Tr18 Turret

About: I make instructables. I also have a YouTube channel at!

Check out my K'nex Breaking Sniper too!

It's the turret for KillerK's gun! The gun is easy enough to build from his slideshow but a lot of people struggled with the turret, so here it is! The TR36 turret is built in the same way, but twice as big!
I have all the necessary permissions. Credit to BakenBitz for the 18 shot concept and KillerK for the design.

Original instructions:

Step 1: Build It

In picture number 1, I have added KillerK's new mod. It will replace the regular ram locks with beige connectors. The only difference it makes is the fact that they are easier to replace if one breaks, so don't worry if you don't have enough pieces! To find out which dark grey connector to replace look at picture 4, the dark grey connector second from the right is what you should replace. 
Picture 1 and 13 are by KillerK

Some pictures are repeated at different angles, so bear that in mind. You should be able to tell which ones.

Step 2: Trigger

Well you're done! Just click the link below to make the rest of the gun. It is very easy as it is essentially just a tube and stick gun. However, I know many people struggle with the trigger mech, so here is a picture of it. Picture was taken by Smilee.

    I like Hiyudaduz's instructions better they are more clear but still these pics were pretty helpful

    parts list for the turret please?

    Can you replace the Grey 1-slot connectors with something else? I only have about 50 of them. Please reply, Cheers :)

    Yes you can, an orange connector would work just as well, make sure you replace the ones that form the barrel parts and not part of the trigger mechanism though, start by replacing all the ones at the front and work your way in!

    can you replace the gray (2 port) connectors to other one`s i don`t have much

    I'm sure you can replace quite a few with an orange connector

    YES FINALLY FINISHED! And I have to say, this gun was definately worth a Saturday screaming in frustration. I couldn't have made the turret without this so... THANKS MAN!

    haha, what did you do wrong? It's probably nothing too hard to fix? I kinda know the feeling: when I first built my SRv2 (there were no instructables of it at the time, so I had to just build it from a few pictures that KILLERK posted) I realised that the barrel was all wrong for the mech and it was a couple of hours and several lacerations on my thumbs later that it was finally sorted XD

    Yay! Finally fixed it! I forget what I had wrong at first, but I know one thing was I had 2 2 space grey connectors on 1 side instead of 3. But it's finally right! On with the rest of the gun! Hurrah!

    i cant get the bullet locks to work can somebody please help me?

    Look at picture 1 and picture 7. See how the dark grey connector of the previous "barrel" leans into the path of the adjacent barrel's firing pin?

    in the last pic how many blue spacers are there

     I'm not sure you'll have to ask KillerK. When I made this I posted the old version, and the last picture is the new one, which I have never made. If he tells you drop a comment here too so I can add it!

    can i ask a huge huge huge huge favor of you? Can you please postinstrictions for the body of the the trifle i suck at building stufffrom pics please please please. That gun is sweet.

     No need, BakenBitz posted the TR36, but the turret sucks. Justmake the body from his instructables then mod accordingly, like the picture
    The gun on the right is the one that accommodates the TR18 turret.
