Picture of M4A1 Sopmod

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.

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.
are the m4s real

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.
The mech seems to be problematic, it wont cock properly.

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.

Np. It's good to know that this can get decent range for a repeater. Thanks for trying it out!
Your welcome.
