Also this gun IS semi-automatic (one pull=one shot)
Step 1: Download.......
Well, i didn't really feel like wasting my next two days Taking the 200+ pictures and uploading them so I built it on Lego Digital Designer (LDD). I actually think it might be a little better on this since it shows the instructions in a 3D format and lists the pieces needed. If you aren't going to build this gun just because you don't want to download LDD then you probably didn't want to build it in the first place since making this gun is going to take awhile.
