Forward Controls Design Sling Adapter End Plate, Hvy, 1 Socket Dlc Blk

The Forward Controls Design sling adapter end plate in heavy-duty DLC black is a direct drop-in replacement for AR-platform buffer tube assemblies, engineered for shooters who want reliable sling attachment without sacrificing wrench access during maintenance. Whether you're running a 5.56 or 308 AR, this end plate solves a real problem: most side-facing QD socket end plates partially block the castle nut wrench notches, making it difficult to properly torque without specialized tools. The FCD design keeps the rear-facing socket unobstructed, giving you full access to all castle nut wrench lugs with a standard three-lug wrench.

Built from 4140 steel and finished in DLC (diamond-like carbon) coating, this end plate delivers the durability you need for field use, training, or competition without unnecessary weight. The single socket configuration keeps things simple and focused: the rear socket has no rotation limiters since the receiver extension itself prevents full 360-degree sling swivel rotation. The side-facing socket design uses rotation-limited geometry to keep slings positioned predictably. The indexing tab ensures proper alignment on your receiver extension, though you may encounter a snug fit on some extensions—something worth checking during installation.

If your setup uses a side-facing QD socket and you've struggled with castle nut access, FCD's approach makes a tangible difference. It's the kind of thoughtful engineering that separates purpose-built AR parts from generic alternatives. Pair it with your preferred QD sling swivel and move forward with confidence that your buffer tube assembly will torque correctly every time.

Frequently Asked Questions

Will this end plate fit my AR-15 or AR-10?

Yes. The Forward Controls Design end plate is compatible with standard AR-platform receiver extensions on both 5.56 NATO (AR-15) and 308 Winchester (AR-10) builds.

What's the main advantage over other sling adapter end plates?

The FCD design positions the QD socket to keep castle nut wrench lugs fully accessible. Most end plates with side-facing sockets partially block one or more wrench notches, requiring a specialized two-lug wrench for proper torquing. This plate lets you use a standard three-lug wrench.

Does the sling swivel rotate freely?

The rear-facing socket has no rotation limiters—the receiver extension itself prevents 360-degree rotation. If you add a side-facing QD socket separately, that socket features rotation limiters to keep your sling positioned predictably.

Will this fit my receiver extension without issues?

The indexing tab should align with most standard receiver extensions, though some extensions may have a tight fit. Verify compatibility with your specific buffer tube before ordering.
