This M1 was rebuilt by Federal Ord, and was stamped by them as a TANKER. A new one piece stock was designed and built to replace the two piece original stock. A Schuster adjustable bleed valve is installed for safety when you use other than Government Spec Ammo. A Smith Enterprise Muzzle Brake is used to enhance shooting abilities. A Rail is attached to the barrel so that a Scout Scope arrangement can be used.
