The Sylvan Arms AR QD Tube Lock Back Plate is a precision-machined replacement lower receiver end plate built for AR-15 shooters who want clean, ambidextrous sling attachment without compromise. CNC machined from 7075 billet aluminum, this black tactical accessory handles the punishment of field use while keeping your setup light and rigid. Whether you're running a dedicated precision rifle, a hunting AR, or a modular platform you swap between roles, a quality end plate matters more than most realize—it's the anchor point for your sling and, by extension, your rifle's handling.
The standout feature here is the three-point QD sling swivel socket, which offers rotation-limited attachment at three different positions. That means you can dial in your preferred sling angle for hunting, transition drills, or just getting behind the gun in your preferred stance, and you can run it the same way from either side of the rifle. No fumbling with adapters; no choosing between lefty and righty friendly setups. Just solid, repeatable sling geometry that works the way you actually use it.
Sylvan Arms backs this end plate with their Limited Lifetime Warranty, so you're covered for the long haul. One compatibility note: this QD end plate does not work with the Gen 2 or Gen 3 versions of the Sylvan Arms AR Folding Stock Adapter, so confirm your setup if you run that specific adapter.

Yes—the Sylvan Arms AR QD Tube Lock Back Plate is a direct replacement for the standard AR-15 lower receiver end plate. If you're running a Gen 2 or Gen 3 Sylvan Arms Folding Stock Adapter, however, this plate is not compatible with that specific setup.
Absolutely. The three-point QD sling swivel socket is designed for ambidextrous use, with three different attachment positions so you can set your sling angle the same way from either shoulder.
The major difference is the integrated QD sling attachment. This plate gives you a clean, solid mounting point for QD sling swivels without needing separate adapters or hardware, and the three-point design lets you fine-tune your sling geometry for your specific rifle and shooting style.
