The ASAP Ambidextrous Sling Attachment Point allows a range of motion greater than 180 degrees, enabling true ambidextrous weapon manipulation for both left and right handed shooters. The ASAP replaces the standard AR15/M4 carbine stock receiver end plate, providing a tactical advantage by minimizing snagging and facilitating easy transition to and from weapon and reaction side shoulders. The ASAP works with Single-Point type slings with snap hook style attachments such as the Magpul MS2 Sling. Made from precision cast black manganese phosphatized steel, the ASAP is compatible with both mil-spec and commercial-spec carbine receiver extensions (buffer tubes). The ASAP has been proved to withstand stress tests of over 300lbs. Made by Magpul. Note: The ASAP is NOT compatible with A1/A2 fixed stocks as well as any other similarly mounted stock such as the Magpul PRS or UBR.
