About: I make K'nex guns, specializing in semi-automatic, RBG-Slingshot hybrid systems which i use in most of my guns. Note: I am not responsible in any way for any damage, injury, or death caused by my Instructab...
This is my MHG-1 (Masterdude Hand Gun model 1). It is not one of my semi-auto's, but a gun which uses a new trigger system which I have not used before (you asked for it you got it). The ammo is handle fed and it's firing pin powered so I could make it more compact. As you probably have noticed (first thing probably) is that it seems to have a hand guard, which it does, but it is also part of a new trigger I designed. Even if my previous guns seemed uninnovative, this gun should make it that you can't say that I don't innovate and do new stuff anymore.

More Instructables by Me

  • True trigger
  • Handle fed magazine
  • Large ammo (well I like it)
  • Doesn't use too many pieces
  • Or rubberbands
  • Trigger is a hand guard
  • Loading ammo can be tricky
  • Trigger can seem wierd to use at first

Step 1: Components

Make the following in the quantities stated. Each component is assigned a letter for further reference:

Image 1: Make 2. A
Image 2: Make 2. B
Image 3: Make 2. C
Image 4: Make 1. D
Image 5: Make 1. E
Image 6: Make 3. F
Image 7: Make 1. G
Image 8: Make 1. H
Image 9: Make 1. I
Image 10: Make 1. J
Image 11: Make 2. K
Image 12: Make 1. L

Step 2: Assembly

Follow the instructions and images:

Image 1: Add blue and white rods to Parts A & B.
Image 2: Add Parts C, F, & K and white rods.
Image 3: Add Parts D, E, F, G, H, I, & J, and blue spacers and gray connectors.
Image 4: Add Parts C, F, & K.
Image 5: Add Parts A & B, and a tan clip.
Image 6: On reverse side add a metallic blue clip and gray connector.

Step 3: Operation

Load the ammo (Image 1) into the mag (handle), and then insert the ammo pusher (Part L). Then add the rubberbands connecting to the ammo pusher and one to the firing pin as well. Then pull back the firing pin to cock the gun, and then pull the trigger to shoot (may take some time getting used to the trigger). Repeat as needed.

    I like this gun very nice. Could you make a new gun with breach loading and the firing pin not being so heavy?

    Why get them breeding then then wait.I guarantee they will die off on their own when something better comes along.

    I don't quite understand what you tried to say, there... All I'm saying is that we have like nine already and they're all very similar, so if a bunch of people start making generic ones then they'll lose what they have going for them >.>

    Or they'll modify them and improve them. I think it would be good for others to try different mechs and try to improve them.

    Lol. Do you know much about this community? For every one person that innovates, there are at least thirty who just stick a stock on the old design and say "omg guys look what I made". And they ALL get posted. This site becomes hugely dependant on trends, and it produces many more...unnecessary items than it should. I'm all for improvement, not starting another trend wave lol.

    However even if there are some spam-like near-copies, as long as someone has posted a real improvement, the community overall has improved. As for those near-copies, one can just ignore them, most people probably do.
