[modeled after RATSLAYER]
this is the same design from http://www.pixelpapercraft.com/photo/568bd2f18fd907e57100001a/sniper-gun-modeled-after-ratslayer
I made this and finally uploading in design. If you couldn't understand this, I will make this that you can understand.
(the made-up gun is little longer so you can cut it if you want)
