Gentlemen this was inspired by DERWOODVW's design it has taken me over 200 hours to modify and test print this design, its a closed bolt carbine that uses a striker to fire the rounds with 5 P-Rails so you can add anything you want, off-course THIS IS ONLY A PROP AND DOES NOT FIRE ANYTHING, There is no Extractor, firing pin or barrel. All building details will be on the make. My next upgrade will be a folding version of this which will be a pack survival rifle hope you like it ;).
