The Forward Controls Design End Plate with 3-QD Sling Swivel Sockets is a premium AR-15 receiver extension engineered to solve a real problem: mounting quick-detach sling attachments without compromising stock collapse or losing wrench access. Built from billet 4140 steel and finished in FDE Cerakote, this end plate combines form and function the way quality gun parts should—no flash, no compromise.
Unlike simpler designs, FCD's end plate accommodates both side-facing and rear-facing QD sling swivel sockets, giving you flexibility in how you rig your carbine. The slightly wider sides and carefully engineered socket openings aren't aesthetic choices—they're structural solutions that let you use stacking castle nuts, allow the stock to collapse fully, and maintain the rigidity you need under fire or in the field. It's the kind of thoughtful engineering that separates solid parts from genuinely useful ones.
One thing to know: if your castle nut wrench is a standard 3-lug tool, the socket housing may block one lug. A 2-lug wrench like the AR Multitasker or FCD's JCW (Joint Castle Nut Wrench) ensures you can torque the castle nut correctly. Also, the indexing tab can fit tight on some receiver extensions, so a test-fit before final assembly is smart. These aren't flaws—they're trade-offs in a design that does more than most end plates.
| Material | Billet 4140 Steel |
| Finish | FDE Cerakote |
| QD Socket Count | 3 (side and rear facing) |
| Compatibility | AR-15 receiver extension |
| Castle Nut Compatibility | Stacking castle nuts; standard 3-lug wrench may have interference—2-lug wrench recommended |
Yes, it's designed as a standard AR-15 receiver extension end plate. Keep in mind the indexing tab can fit tight on some receiver extensions, so a test-fit before final installation is recommended.
A conventional 3-lug castle nut wrench may not access all lugs due to the socket housing. FCD recommends a 2-lug wrench like the AR Multitasker or their JCW for proper torquing.
Three QD sling swivel sockets—positioned to accept both side-facing and rear-facing quick-detach swivels, giving you options for how you configure your sling.
Yes. The end plate is engineered to allow full stock collapse and supports the use of stacking castle nuts for flexible configurations.
