Knex AR-12 Prototype II (How to Build)

About: Hi. I've sold off about 99% of my k'nex, but I still come here to check in on instructables, every 2 weeks or so. I like seeing what's new in the k'nex, and also other sections. I may or may not post my K'n...

I got enough requests from various members to post this gun. This gun is very simple and does not eat up too many of your parts. Its easily customizable for sights, scopes, and a grip.

Supplies:

Step 1: Stock

This is the stock of awsomeness. Follow the pics.

Step 2: Mag/Barrel/Trigger

Simple, follow the pics.

Step 3: Handle and More Barrel

Simple.   

Step 4: Assembly

Very Simple.

Step 5: Yayz! You Earn a Cookie!!!

No really, you do. Show me a pic of the completed result.

    Cool, perhaps it's time to make something different than a gun with a standard mag and ram, try to make some concepts and build them!

    Try make a revomable mag, pump-action shotgun, or a slingshot gun with a mag.If you do try these, I look forward to seeing what they turn out like.

    P.S. I've always been a fan of you guns, you've got a great designing capability and getting a strong build in a good looking gun.

    You know, duck tape is like the force.
    It has a dark side, and a light side.
    And it holds the universe together.

    Oh really? I'm actually here quite often, I just don't comment very often. But good point, he did spam by posting a link to a remake of a rather terrible quality gun.

    Is the trigger always so hard to pull...mine seems to take a lot of force to make the gun fire D=

    That can't be right. Back when I had this gun, the trigger pull was fairly easy. It shouldnt need a ton of force to pull it.
