Forward Controls Design End Plate W/ 3-Qd Sling Swivel Sockets Black Dlc

The Forward Controls Design end plate with 3-QD sling swivel sockets combines purposeful engineering with practical versatility for your AR platform build. This billet steel component serves as both a receiver extension cap and a dedicated sling attachment point, letting you deploy quick-detach sling swivels from the side and rear of your rifle without adding bulk or relying on improvised solutions. The black DLC finish provides a durable, low-glare surface that resists corrosion and wear in field conditions.

FCD's design philosophy shows in every detail. The end plate accommodates side-facing and rear-facing QD socket openings while maintaining the structural integrity to work with stackable castle nuts and allow your stock to collapse fully—a balance that requires thoughtful engineering rather than brute force. You'll notice subtle widened sides and small openings on the socket housings; these aren't cosmetic but functional, ensuring the plate does its job without compromise. The indexing tab on the receiver extension is engineered for proper fitment, though some receiver extensions may require a snug fit.

One important note if you're building or upgrading: end plates with side-facing QD sockets can occasionally interfere with standard 3-lug castle nut wrenches by partially blocking access to the wrench notches. If you encounter this during installation, a 2-lug wrench (such as an AR Multitasker or JCW) provides the clearance needed to torque your castle nut properly. The robust billet 4140 steel construction means this plate will outlast many barrels, making it a solid long-term investment for any serious AR owner.

Frequently Asked Questions

Will this end plate work with my AR-15 carbine stock setup?

Yes. The design accommodates stackable castle nuts and allows your carbine stock to collapse fully. Note that the receiver extension indexing tab may fit snugly on some receiver extensions, so check fit during assembly.

What castle nut wrench do I need to install this?

A standard 3-lug castle nut wrench works in most cases. However, the side-facing QD socket housings may occasionally block one of the three lugs. If you experience this, a 2-lug wrench (like an AR Multitasker or JCW) provides the clearance you need to torque properly.

Can I attach sling swivels from multiple angles?

Yes. This end plate includes two side-facing QD sling swivel sockets and one rear-facing socket, giving you flexibility in how you rig your sling to your rifle.
