The FN 15 Patrol Carbine LE offers the same features as the standard FN 15 Carbine model but has an alloy steel, button broached, chrome-lined barrel, Samson flip-up rear sight for compact and reliable back-up sighting and a Midwest Industries drop-in 7" quad rail hand guard for increased adaptability and front gripping options. This model comes with a GI-pattern aluminum magazine with low-friction follower.
