The PRFCS slips through the rear sling slot of most M4-style collapsible stocks and adds a rugged 3-inch side Picatinny rail. Molded from fiberglass-reinforced, high-density polymer, it lets you mount CAA’s ACP adjustable cheekpiece, SSM 12-ga shell holder, or any rail accessory in seconds—no tools, no permanent mods. Choose right-hand or left-hand orientation to keep controls clear and ergonomics intact.
