These are either factory new, or lower receiver take-off new and repackaged.
Contains the lower parts kit for the Colt M4 semi-automatic receiver, less the fire control (trigger group). This is convenient if you are looking for the best in solid performing lower parts, but are using a trigger upgrade kit, like Geissele, LMT, KAC, etc.
This has the newer style safety with the main lever a little shorter and not extending into the middle of the axle, and with the directional arrow on the left 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.
All 100% Genuine new Colt parts. May contain oil (that is good).
