ProMag PM140A Sling Attachment Plate Single Point Dual Loop Black Oxide Steel

The ProMag PM140A ambidextrous dual loop single point sling attachment plate replaces the collapsible 4 or 6 position butt stock retaining plate on rifles equipped with adjustable stocks, converting the rear of the weapon for use with a single point sling. Built in the USA from black oxide carbon steel, this drop-in adapter features twin loops that accept HK-style hook or clip-style single point slings, allowing the firearm to be carried comfortably on either the right or left side.

The PM140A installs in place of the factory buttstock plate without permanent modification, making it a popular upgrade for AR-pattern rifles and other platforms that share the same collapsible stock interface. The black oxide finish provides corrosion resistance and a low-glare appearance, while the all-steel construction ensures the attachment point can handle the repeated stress of shouldering and dynamic movement with a single point sling.
