About: I'm an intermediate knexer who builds replica guns and performance guns. If you would like me to make a replica of a gun, just ask. If you would like me to build your gun and review it, just ask. My gamertag...


Well, here it is. It operates on a simple rubber band loaded firing pin design, which transfers energy to the ammo after being released by the pivoting trigger mechanism. Shoots grey connecters with green rods, removable mag, pin guide, has a charging handle, and is almost completely 1:1 scale.
Have fun.

WARNING:REQUIRES CUT PARTS

Step 2: Reciever

Step 4: Magazine

These are detachable, internally pushed, and roofed. Read the image notes. They contain the instructions. Make as many as you can. load with One slot grey connectors with a green rod in the slot.

Step 6: Done/Gallery

Here's your cookie. Use the band on the trigger guard to band the mag release if you haven't already done so. Band the Pin however you want. With 1 string of 2 #64s, I got a nice 30 feet. Have fun! If you make this, I will post your pic on this step. if you have a nice attachment you want in the 'ible, I'll make a step for it.

    i have the same cookie in one of my ibles

    anyone having a problem where it shoots one bullet and ejects another at the same time?

    The magazine pissed me off so much, but i finally finished it haha. This gun shoots great! 5 stars.

    ok, cool.. maybe it was an annoying little kid

    Does it use many red connectors

    Als ik goed heb geteld: 26 witte en 12 blauwe verbindingselementen.

    Dankje ik zat rond hetzelfde getal ;P

    Thanks! Idk, k'nex kinda bores me. nothing new worth making I guess.

    Same, I come on like every 2 weeks and its just becoming less and less.

    Try using a different rubber band/banding method on the blocker. Or, try modifying the blocker.

    Thank you, that helped =) My version shot about 46 ft on average with 4 # 64s on it. But sadly I destroyed it; although i have kept your amazing trigger guard and pistol grip for my new Compact Shotgun aka BCS2.
