About this 3D model

I present you, my Nerf M4 (look alike) barrel I was looking for something to convert my Nerf Strafe into something more m4 like.Since i didnt found all to much, i decided to make something myself. after all thats what we are here for right? ^^ The inner of the Barrel comes from ornotermes (see remix).I just gave it a few holes, extended it a bit, mounted another Nerf barrel coupler on top of it and gave it a few rails.
