FN 15 Military Collector M4 5.56x45mm NATO 16" 30+1 Semi-Auto Rifle

The FN 15 Military Collector M4 is FN's faithful civilian replica of the U.S. military's M4 carbine, chambered in 5.56x45mm NATO and built to the company's exacting production standards. This semi-automatic rifle bridges the gap between FN's duty-grade military arms and the modern sporting rifle market, giving collectors and sport shooters an authentic M4-platform experience straight from the factory.

At the heart of the platform is a 16" button-broached, chrome-lined barrel with a classic government M4 profile and a 1:7" right-hand twist that reliably stabilizes a wide range of 5.56 NATO and .223 Rem ammunition. An A2-style compensator is fitted at the muzzle for traditional flash signature and recoil management.

The aluminum receiver carries the Military Collector Series' UID-labeled lower receiver - an authentic military-traceable marking - and is finished in a non-reflective matte black. The fire control group is paired with an ambidextrous safety selector for easy manipulation by right- and left-handed shooters alike. Up top, the rifle wears traditional A2 fixed front sights paired with an adjustable rear sight, and the flattop upper is also optics ready for mounting a red dot or low-power variable optic.

Controls and furniture stay true to the M4 lineage: a 6-position collapsible buttstock with integrated sling mount adapts length of pull for different shooters and kit, and a classic black A2 pistol grip keeps the manual of arms familiar. The rifle ships with a 30-round detachable magazine, giving shooters a full NATO-spec loadout right out of the box. Overall length runs 30.50" to 34.20" with the stock collapsed and extended, and the rifle tips the scales at roughly 6.60 lbs.

Whether you're looking for a duty-pattern training rifle, a stand-in for a service-issue carbine, or a collectible M4-pattern semi-auto from one of the world's most respected arms makers, the FN 15 Military Collector M4 delivers authentic FN quality in a modern sporting rifle configuration.
