Contains full lower parts kit for the Colt M4 semi-automatic receiver, including fire control (trigger parts), A2 grip and port-side (left) safety selector. All 100% Genuine new Colt parts. May contain oil (that is good). In 2021, the parts changed a little, with the hammer and safety changing. This hammer has the notched version and the safety lever extends further into the middle of the shaft on the left side, and there is no indicator arrow on the right side.
Colt standard safety selectors are one of the only safety selectors which can be installed from the left or the right, so while technically not ambidextrous, this safety can be installed on the left side or the right side with equal operating effectiveness.
