Fn 15 M4 Military Collector 5.56x45mm Nato 16 in 30+1 Matte Finish Optics Ready

The FN 15 Military Collector Series M4 is a military-replica rifle built to FN's exacting specifications and engineered for shooters who want authentic M4 ergonomics in a semi-automatic 5.56x45mm NATO platform, with a 16-inch 1:7" RH button-broached, chrome-lined barrel that resists wear and maintains accuracy during heavy use. Outfitted with a matte black, six-position collapsible stock and a familiar A2 grip, the aluminum lower features UID labeling and an ambidextrous selector for intuitive handling from either shoulder, while the optics-ready upper accepts modern red dots or low-power variable optics for both range work and duty-style applications. The rifle's 30+1 capacity, A2 compensator muzzle, A2 front and adjustable rear sights, and 1:7" twist make it well suited for training, competition with heavier-profile 62×77 grain bullets, and defensive scenarios where controllability and follow-up shots matter; its 6.60 lb weight and 30.50"×34.20" overall length balance maneuverability and stability. As part of FN's Military Collector Series, this model preserves authentic M4 features—chrome-lined barrel, button-broached rifling, collapsible stock—while remaining compliant in semi-auto form for collectors, range shooters, and tactical trainers who want a service-style rifle that's optics-ready and built to last.
