SMG & Stock.




Here is small compact gun i made, Reminds me of the SMG. I also added a stock to the design, to make it more stable and allow for a more precise shot. It is not really bringing in any new ideas to the table, it is just a new design. Hope you like it and can follow the instructions easily. Any ideas for improvement or look would be greatly appreciated.

Step 1: The Barrel & Handles.

If you look at the below image, you should easily know what you need to make these parts. Also you should have a idea on how to make it too. If you have any questions on how to make these parts, then please leave a comment.

Step 2: Stock.

The stock is fairly simple just join all the parts together as shown. Do not connect it to the rest of the gun, until you have placed the ram into the barrel. To save yourself time and frustration of taking it apart all the time.

Step 3: The Ram.

This is not that hard, just connect in as shown in the picture. As a tip, use Cello tape to stick the pieces to the actual rod. ( Only the Grey piece ) Saves it from disconnecting when loaded and also with enough tape in the way. It can absorb much more pressure when using more elastics. ( More power )

The Brown little pieces at each end, allow the ram to run smoothly across the top of the stock. Also giving a easy reload, by pulling it back.

Step 4: Setting Up the Elastics.

The main elastic for the trigger should be stretched as shown in the picture. The other elastic should be coming from the back of the ram to the very front resting on the two Grey tips of the rods. It is up to you where you would like to tuck the stretched elastic. I would recommend tucking them underneath the red pieces, in the groves. Out of sight.

Step 5: Connecting the Stock to the Gun.

Tip: Do all this after placing the Ram into the barrel, then get all the elastics on now before connecting the stock.

You probably already know where you have to connect everything. Make sure the Grey rods on the stock clip into the Yellow pieces on the Barrel. Also remember to clip the other Grey rod underneath, where the space is.

Step 6: Finished.

Thats it, just make sure all the parts are connected well.

This Gun fires: Green pieces, White rods, blue rods and also Yellow rods.

Tip: I would recommend using the blue and Yellow pieces.

Hope this was easy to understand, i would appreciated comments for improvement and looks.

    Well, not really, i built your gun (awsome range btw ;) and i couldn't be bothered building another one so i stripped your guns firing system, and made it true trigger, then i added a handle and some cosmetics and "Hey Presto" an AK-47

    This does not look like an AK-47. You could maybe pick out features like the Stock, ( Maybe ) or the shape in the middle. Still it is to long at the front. However, i do like that you have made a True trigger. I have seen this same trigger mechanism before, not really new. But hey, at least you are coming up with ideas upon how to make it better. Here are some new shots, i have added a lot more strength to it now. The barrel was redesigned again, Stock too. these two alone made it easier to load and fire. Also if you remove the handle on top and look down the the barrel you have a great sight. ( You line up the white back piece, with the front orange piece. ) I have never missed a target yet. Also as i have not yet got round to making a guide, maybe the more creative of you could create it from these pictures. Any questions, i will answer. Hope you like the design and ANY ideas for improvement or look, would be greatly appreciated.
