The FN SSR fully adjustable rear stock assembly transforms your SCAR 16S or SCAR 17S from a general-purpose carbine into a precision shooter's platform. Built from black aluminum, this toolless stock lets you dial in length of pull and cheek height on the fly—critical tweaks for consistent accuracy whether you're working supported prone or bench. If you run your SCAR in a DMR or precision rifle role, this is the ergonomic upgrade that pays dividends downrange.
What sets the SSR apart is the absence of fiddling. Push the adjustment lock to modify length of pull; press the cheek rest riser and pull upward to dial cheek height. No tools, no guessing, no breaks in your setup. The MIL-STD M1913 rail molded into the bottom of the stock gives you a standardized hard point for monopods, sling attachments, or other supported-shooting aids—the kind of rail real rifle builders expect.
Aluminum construction keeps weight minimal without sacrificing rigidity. If you're used to adjustable stocks on AR platforms, you'll recognize the concept here—but the SSR is engineered specifically for the SCAR's profile and controls. It's the kind of refinement that whispers confidence during long-range sessions and shows up in tighter groups.
