The Magpul Ambidextrous Sling Attachment Point replaces the standard AR-15/M4 carbine stock receiver end plate with a receiver plate that provides an ambidextrous sling attachment point. This minimizes sling snagging and provides an easy transition to and from weapon and reaction side shoulders. The Ambidextrous Sling Attachment Point works with single point slings with snap hook attachments such as the Magpul MS3. Made from precision cast steel with a black manganese phosphate finish. Compatible with both Mil-Spec and Commercial carbine receiver extensions. Made in the USA.
