Introduction: Knex Tube Fed Rifle

About: I am I _____. Lord of ________. If you can fill in those blanks you a well read person. Also please comment if you can fill in those blanks and what you can think goes in the blanks. I have been meaning to m...

If you need more information or are unable to understand anything, please feel free to ask. I will try to respond in AT LEAST 24 hours, though I make no promises or guarantees that I will, because as we all know stuff happens.

If you see any errors in my grammar or spelling pleas feel free to point them all out.

Step 1: ​Gather Pieces

Step 2: Magazine and Barrel

This was the longest step. You build the magazine and the barrel.

Step 3: End

Step 4: Handle

Step 5: Finishing Up

Note: The next steps are the optional features.

Step number 6 is the fore grip.

Step number 7 is the stock.

Step number 8 is the scope.

Step 6: Fore Grip

Note: It can be mounted in two ways.

I did NOT come up with this fore grip. This fore grip was made/designed by the Red Book Of Westmarch.

    i am gonna try to build it again, see if i can make some cool changes, like a pin guide. and replace the tube feeding mech with a magazine feeding mech. Can i send you some pics to upload or may i upload instructions for my own modded version of it

    You can definitely send me pictures if you want. You can also upload your own instructable for your version. What keeps failing? The one I have posted, with no modifications or your attempts at trying to make it better? I have been trying to fix it up myself with many failures to get the changes to work. If you want I can post some pictures of what I have so far. The mechanics of the gun (as posted) are quite complex. I Hope you have better succes at modding this than I have had.

    sorry man, it keeps failing on me

    and if i remember there are no bendable orange conectors, or do you mean other orange connectors that i don't know about

    Never mind, I see what you are talking about. I think I meant to say bendable orange rod, but as far as I can tell there are no bendable orange rods used in this build. Sorry about replying a long time later (it might have been even longer because I only noticed these comments because I couldn't remember how to put the trigger back together and had to pull this up). I am currently redoing this gun. As much as I love the mechanics behind the tubular magazine, I wasn't able to get it to fully work. I am adding a removable magazine and (If I can get it to work) making it a bolt action. I have also changed how the for grip is attached to the gun.

    I'm sorry guns are not my domain. Ask some awesome gun builders on the site, they can help you better than I can :)

    Can you explain why it is layed out in the gun a wierd way?

    Try replacing the grey connector with a small blue clip. That way, the connection to the green rod is sort of guarded between the blue spacers and light grey connector, making it somewhat stronger.

    Do you have a picture of this? What does a small blue clip look like? Thank you for this idea/suggestion I will implement it as soon as I can see what I am doing. It sounds exactly what I was looking for.

    I can't use my K'nex right now, since everyone here except me is asleep, but I can put something together tomorrow, if you'd like.
    Here's an image of the blue clips I mean. The trigger will have to move up a bit more, but it should be sturdier than it is now.

    Sadly I have tried all of those already, though I forgot to mention it above. Also When I take off only 1 rubber band the range of the gun drops by half. I do not know why 1 band should affect the range so greatly but it does. What do you think of the gun? Also do you have any more advice on how to improve it or a design for a even stronger trigger?

    I'm not one for making guns shoot, you'll have to ask other members for that sorry :/

    try lowering the trigger and replace the end with one of these to block the ram, as these are better at blocking because they're square, the one you're using is round and will be pushed down by the pressure, also try scotch or duct tape (a tiny bit ducttape) and if all fails, try hotglue(I am NOT a suporter of glueing knex but it seems to help some people)

    Also try lowering the amount of rubberbands, that might also do it.
