ProMag PM140A Ambidextrous Dual-Loop Sling Plate | PM140A

Made in the USA, the ProMag PM140A is an ambidextrous dual-loop single-point sling attachment plate that replaces a collapsible (4- or 6-position) buttstock retaining plate. It accepts hook-style, single-point sling hardware through its dual loops and permits the rifle to be carried on either the left or right side. Constructed of carbon steel with a black-oxide finish, the PM140A is intended for use on AR-pattern collapsible stocks and similar platforms. Typical applications include range training and competition shooting where a single-point sling mount and ambidextrous operation are preferred.
