    Sorry it took a while, but it's up there now!

    Hey shadowninja im new and i made some mods for your gun and i was wondering if i could post them

    I'll need you to send some pictures and info or something but sure!

    (this comment is only for people who want to accept this challenge) If you can, I want to see if anyone can make a knex version of the Nerf Vortex Nitron. I will leave some pictures of it in my profile. If you want to try this, comment below this comment. If you think you have succeeded after making it, comment below the acception of the challenge.

    Hey, I modded both mags a little bit, because for some reason, the ram would knock the mag out of the gun. So I added some parts and cut some parts to fix the problem. I will try to upload some pics that show what I did. :)

    Interesting. Yeah that would be helpful I'd like to see what went wrong.

    Actually, I just made it again (because I had taken it apart) and I found out why the ram would knock the mag out of the gun. It was because the mag wasn't in the gun right. So I put it in the right way, and the ram doesn't knock it out.
