The FN SSR Rear Stock Assembly (brand part no. 20100566) is a precision upgrade stock built for FN SCAR 16S and 17S rifles, converting a standard SCAR into a DMR-style precision platform. Machined from black aluminum, it’s fully adjustable for both length of pull and cheek height, and every adjustment is made without tools: pushing in on the adjustment lock lets the buttpad extend or collapse to the desired length, while pressing in on the cheek rest riser and pulling upward raises the cheek height to the correct level. The stock is designed to improve ergonomics for supported prone shooting positions, and it includes a MIL-STD 1913 rail on the rear for mounting a monopod or other accessories that aid a supported firing position.
