FN FN15 COLLECTOR M4

FN’s FN15 MIL Collector M4 is the closest thing to a “real deal” M4 vibe without the government paperwork. You’re getting a chrome-lined, button-broached 5.56 barrel (14.7” with a pinned A2 comp to make legal 16”), 1:7 twist for the modern ammo crowd, UID-marked lower, ambi selector, and that classic Knights-style M4 RAS with rail covers. Flat-top for an optic, A2-style sights for nostalgia, and a 6-position stock to fit you (and your kit).

All the M4 feel—none of the compromises.
