Semi-automatic rifle restrictor mechanism

Abstract

A production AR-style semi-automatic rifle (i.e. AR-15, AR-10, M-16, M-4, etc.) that has been converted to a single shot rifle includes: a) conventional rifle components, including a receiving trigger, trigger guard, barrel; b) a semi-automatic firing mechanism including a gas actuated casing ejection and bolt reset mechanism including a bolt carrier with two carrier gas key threaded receiving orifices and having no production carrier gas key and a having a dual-bored metal block gas blocking restrictor mechanism attached to the bolt carrier and positioned so as to inhibit\semi-automatic operation of the AR-style semi-automatic rifle by disabling the automatic gas actuated casing ejection and automatic gas actuated bolt reset functionality. In some embodiments, there is a modified charge handle having an extension with two attachment orifices corresponding to the metal block gas blocking restrictor mechanism orifices and is coincidentally attached to the bolt carrier. There is also a method of converting a AR-style semi-automatic rifle to a single shot rifle.
