Editor’s Note: The FN 15 Patrol Carbine has the same features as the standard FN 15 Carbine model but with a 16” button-broached chrome-lined barrel, Samson flip-up rear sight, and a Midwest Industries carbine-length quad rail hand guard. Equipped with the standard A2 furniture and an A2 front sight block, the FN 15 Patrol Carbine is a basic, no-frills, reliable carbine that is well suited to patrol and hard-duty use.
