    Best thompson on the site, IMO. The looks are great, except the trigger guard doesn't seem right for some reason. Also, I enjoy the color scheme, you should use it more often.

    Thanks Corgi, I think this is the best K'nex Thompson on Instructables. The metallic colours was a one off scheme and I may or may not use it again and also I don't see anything wrong with the trigger guard

    Thanks Sand, I did it in those colours because I wanted to see what it would look like in a darker colour compared to the usual brighter pieces.

    Ok, just another gun on my build list! I just have to wait for my pieces to come (Mid-End April) and I can then make many guns at a time!

    Thanks Akshat, can't wait for the PPSh-41 and Ray Gun Mark II as well, like you said you would build. If you can get pictures of them, that would be great.


    This looks sweet! However, one of the things I've noticed with this, and your earlier posts, is about the broken pieces. Quite a few of the broken rods you add in the parts list aren't needed, you could just replace them with normal one. In this one, mainly in the foregrip. Of course, the use of broken rods is up to your preference, just pointing that out ;)
    Anyway, it looks great, and the instructions look clear, good job.

    Thanks Doc, there will be more instructions on the way. I know that there are cut pieces in nearly everything that I post on instructables, I use cut pieces to make my models more realistic so it looks like the real thing. There are cut pieces in the foregrip to make it more comfortable to hold as if I had put in normal rods, they would stick out of the foregrip and make it very uncomfortable. Have you look at my other instructions and is there anything you might build =)

    I understand why you would use broken pieces to make it comfy. I have looked at all your ibles so far, that Mystery Box was pretty darn impressive!
    I didn't build any of the things you posted though. Overall, I'm more someone that builds his own stuff, y'know? But the things you post are good!

    Good job on the overall appearance of the gun! This would be really easy to make a shooting model of this so I'm going to add this to my build list.

    Well to be honest. I did try the foregrip on Competitor IV and it didn't look the way I wanted to. The barrel was to short. I haven't played with the ray gun mark II yet either. However after I build Competitor V
