ProMag Receiver End Plate Loop Sling Mount Adapter AR-15, LR-308 Carbine Steel Black

A single-point sling transforms how you carry and deploy your AR-15 or LR-308, and the ProMag Steel Receiver End Plate Loop Sling Mount Adapter makes that setup straightforward. This adapter replaces your standard mil-spec rear receiver plate and provides integrated loops for quick, tool-free attachment of any hook-style single-point sling. It's the kind of upgrade that takes minutes to install but pays dividends in the field—whether you're moving between shooting positions, transitioning from carry to ready, or just need a more practical way to keep your rifle secured and accessible.

Built from carbon steel and finished with black-oxide treatment, this mount is made to handle hard use without fuss. The dual-loop design is ambidextrous, so you can configure your sling carry for either shoulder depending on your shooting stance, position, or just what feels natural that day. No special hardware or adapters needed—it works with standard single-point sling attachments and drops right into the receiver end plate position on mil-spec uppers.

ProMag manufactures these adapters in the USA, and the straightforward design means there's almost nothing to break. If you've been running a two-point sling but want the speed and flexibility of a single-point system, or if you're building out a new AR platform from scratch, this is one of the simplest, most reliable ways to get there.

Frequently Asked Questions

What slings work with this adapter?

The ProMag adapter accepts any standard single-point sling with a hook-style fastener. The integrated loops on the plate are sized to accommodate typical military and commercial single-point sling attachments.
