Lego Blowback-action Pistol

This is my lego blowback pistol that I made. It is the first lego pistol that I have attempted to build, so don't expect it to be awesome. It isn't really a true blowback, because only the back part of the barrel moves. Anyway, let's get to the pieces you will need.

Follow the pictures, the ending result should resemble the first image given. For the rubber band any one would work as long as its not ridiculously tight or too loose.

Make the first side and then put the trigger assembly where it is shown in the picture, the trigger is not connected to the frame, it is just loose and unconnected. Make the second half of the frame and attach it to the main assembly make sure the trigger has room to slide. Then add the one by four and your done.

For the handle I tried to use new building techniques that I haven't used before, so it was probably the part that I put the most effort into. Build the three main assemblies and then connect them to the main build as depicted in the images, then the rest is self explanatory.

Assemble the barrel and be sure to loop the rubber band around the blue pin.

Your done.
