Description
Slings make a rifle easier to carry, steadier to shoot, and quicker to shoulder, but a lot of AR-15 lowers don't come ready to run one. The Ergo Double Loop Sling Plate fixes that by replacing your standard receiver end plate with a version that has a solid loop on each side. It's a clean, low profile way to add a proper mounting point without bolting extra hardware onto your rail or buffer tube.
Ergo machines this plate from 1018 carbon steel, so it's built to take the pull of a loaded rifle hanging off your shoulder all day. The double loop layout is fully ambidextrous, which means you get an attachment point on the left and the right. Righties, lefties, and anyone who likes to switch shooting shoulders can set up a single point sling exactly the way they want it.
What the Ergo Double Loop Sling Plate Actually Does
The rear of the receiver is one of the best spots to hang a single point sling because it keeps the rifle balanced and close to your body. This plate puts sturdy steel loops right there at the back of the lower, giving your sling clip or split ring something strong to grab onto. No adapters clamped to the buffer tube, no bulky attachments getting in the way of your cheek weld.
Installing the 4970 Sling Plate on Your AR
If you've ever swapped a castle nut, you already know the drill. The plate slides on in place of your existing end plate between the buffer tube and the castle nut, so there's no permanent modification to the rifle. It works with standard M4-style collapsible stock setups, and once it's torqued down you've got two ready sling points that aren't going anywhere.

Frequently Asked Questions
Is the Ergo Double Loop Sling Plate ambidextrous?
Yes. It has a solid loop on both the left and right side of the plate, so you can run your sling on whichever side suits you. That makes it a good fit for right handed shooters, lefties, and anyone who switches shooting shoulders.
What is the double loop sling plate made of?
Ergo machines this plate from 1018 carbon steel. That gives you the strength to trust it with a fully loaded rifle hanging off your shoulder without worrying about the loops bending or failing.
How does the 4970 plate install on my AR-15?
It replaces your standard receiver end plate. You'll loosen the castle nut, swap the plate in between the buffer tube and the castle nut, then torque everything back down. If you've done any basic buffer tube work, it's a quick job with no permanent changes to the rifle.
What kind of sling works with this plate?
The rear loops are ideal for a single point sling, which keeps the rifle balanced and close to your body. You can attach a sling clip, snap hook, or split ring to either loop depending on your setup.
