Select fire AR lower reciever

I saw an AR receiver at a pawn shop today that was marked full-auto, semi-auto safety.


It had the markings at the selector switch for full, semi and safe.

What would it take to build this rifle legally.

    It is the presence of the auto sear pin hole above the selector that indicates whether or not the receiver is semi auto or select fire. You can build it up as a standard semi auto but the use of an M16 selector is prohibited in AR semi autos.

    Was it a Spikes Tactical lower like this one?

    Description:

    Semi-auto lower receiver is machined from a 7075 T6 aluminum forging to mil-spec dimensions for precise fit and outstanding performance. Ruggedized hardcoat anodized finish resists scuffs, scratches, and wear. Stamped and color-coded bullet selector position markings notify operator when weapon is in "safe" or "semi-auto." A "full-auto" position is not selectable but gives this semi-auto lower receiver the appearance of being multi-burst capable. Magazine well features Spike's spider logo and multi-cal engraving. Stripped Lower comes as a standalone component without trigger group, mag release, selector, or bolt release.

    I didn't look close. Then he grabbed it up and bought it. The attendant said they had more to put out, so I am going to find out tomorrow. Thanks for the insight.

    No full autos manufactured after '86 are possible for the average person.

    Thank you my experts! I stopped in there today after work and checked out the stripped receiver. It was not designed for full-auto capabilities.

    As some of you had revealed, it was just markings on the receiver for looks.

    The manufacturer was some small name from southern Idaho.
