    Well not to worry mate =D I have one with instructions lol. Here it is =D

    sorry i was just tired of seeing all your amazing guns and not getting to build them thanks it really helped thank you

    hurricane coming soon

    ya i had to delete it becuase it was way to long, i sow your new AR-8 gun with the new mag but i say that the prototype mag was better becuase it was already done with the hang down mag,then the top hopper was not done by alot of people.

    That is true about the hopper, but the mag makes it work much smoother, and it can fire much faster without jams.

    ya that is good,but it has still been done.

    Well im starting a secret project for the 4th of July.

    what is it tell me on the inbox please=D(me to i am working on a secrete project to.
