*2 PVC pipes (any length/size but not too thick)
*Electrical tape-orange and black (Duct tape works too but this is better)
*A PL61 laser (not really recommended,you can use others but this is the best one to use for me....) Oh and the laser needs to be removable from the cartridge that you attach on the rail or if you cant find it is fine. :D
>>P.S. the laser above is not a PL61, it's just what I can find in the internet...
