This is a working parts gun with all parts. The barrel has been cut and the gas system is not in place but the gas parts have not been altered. I fires but probably will not semi with the gas system removed.The stock is a custom monte carlo. There is extra flash suppressors and new extra firing pins.and other parts. The receiver has some indents where scope mount set screws were mounted. All parts look and function great.I will email pics of all parts if interested.
