The ProMag PM140B Single Point Sling Attachment Plate is a carbine accessory built to replace the retaining plate on your collapsible stock and enable single-point sling setup. Whether you're running a modern tactical carbine or a practical hunting rifle, a single-point sling offers fast transitions and the ability to wear your rifle on one shoulder without fumbling with traditional two-point geometry. This black oxide steel plate lets you hook a single-point sling directly to your rifle, so the gun hangs ready and stable at your side—left or right, depending on your preference and shooting stance.
The plate mounts where your original collapsible stock retaining plate sits, so installation is straightforward for anyone comfortable with basic takedown. What sets single-point attachment apart is the flexibility: your rifle can collapse or extend without affecting sling length or binding, and the setup works whether you're left-handed or right-handed. The black oxide finish is durable and low-profile, blending in rather than catching light or snags.
Carbon steel construction keeps costs reasonable without sacrificing strength for a component that handles only sling load, not structural support. If you're building a patrol rifle, upgrading a home-defense carbine, or just want better carry options than a two-point sling offers, this plate is a cost-effective foundation for that mission.
| Material | Carbon Steel |
| Finish | Black Oxide |
| Application | Collapsible stock retaining plate replacement |
| Configuration | Left or Right Hand selectable |
The PM140B is designed to replace the retaining plate on collapsible stocks with 4 or 6 position adjustment. If you have a standard AR-pattern buffer tube and collapsible stock, this plate should fit, but confirm compatibility with your specific stock model before ordering.
Yes. The plate can be assembled as either a left or right-handed attachment, so you can configure it to suit your dominant side and sling preference.
No. The plate allows your stock to collapse or extend normally without binding or requiring sling length adjustment—the sling loop stays functional at any stock position.
This plate provides a loop for single-point sling attachment. You'll need a single-point sling with a hook or loop that fits the attachment provided on the plate.
