Knex Mosin Nagant




Hello, and welcome to my Instructable on how to create a Mosin Nagant out of K'nex.
This gun is a slingshot type gun.

...And well yeah, it kind of bends but it took me a day to build :P
So time to...BEGIN!

Step 1: Make the Barrel

Look at the pictures, and read the notes please.

Step 2: Make the Main Body

Look at the pictures and read the notes please.

Step 3: Make the Butt

If you are immature like me you will probably laugh at the title.
But really, make the butt of the rifle by looking at the pics and reading the notes please.

Step 4: Make the Scope

Alright, so look at the pictures and read the notes...again.
This is quite easy I hope, I mean like really. :P

Step 5: Make the Trigger

Read the notes...actually you should just have to look at the picture!
The trigger is by Lowney.

Step 6: Connect Everything! + Rubberband Placement

Read the notes, look at the pictures.
You know what to do..

Thanks for building this by the way!
Use whatever ammo you can, but it must have a grey connector attached to it! (So it can clip onto trigger).

    got any idea what it stopped on?

    because of the length of the fake barrel, you need a lot of power and good rubberbands... otherwise any bullet would catch on that length...

    Might I make a suggestion? Do not, I repeat, do not use rubber bands. They are weak, they break, and they are awkwardly placed in just about any K-nex configuration. I suggest you use springs, they are much more powerful and I would imagine that they would be much easier to configure into a bolt action system.

    im afraid your wrong there

    i made a spring powered gun, and the spring is too powerful to hold back with anything but a block trigger.

    and a spring that was any weaker would not have gotten good range.

    An interesting point.
    Might I ask, however, What type of spring did you use?
    Was it something from an airsoft spring rifle, or was it a compilation of pen springs?
    I managed to make a simple spring gun that could send a throwing dart almost sixty feet. I may have to reconfigure the bolt system for the sake of the shooter's comfort, but it works and it's spring powered.
    All I am saying is that rubber bands are not very reliable after attempting to fashion a few kNex guns myself. I believe that springs are more reliable and can be applied to a kNex medium much easier than a band could. 
    What are your thoughts?

    uuh the spring i used wasn't a small pen type spring...

    it was pretty strong and prolly something you'd find in an airsoft gun, though i don't really have any myself...
