Forward Controls Design - Sling Adapter End Plate - ESF-H1

The Forward Controls Design Sling Adapter End Plate (ESF-H1) is FCD's low-profile enhanced sling attachment end plate for AR-15/M16 carbine lower receivers. The ESF (End plate, Sling, Forward Controls) series replaces the factory mil-spec end plate with a piece that integrates a QD sling socket directly into the end plate — providing a secure, rock-solid sling attachment point at the rear of the lower receiver. The H1 variant features a single sling attachment point on the left side (right-side friendly for standard shooting position). Machined from billet steel, the ESF maintains full compatibility with the castle nut and provides a reliable, non-rotating QD socket for one-point or two-point sling configurations.
