Foxtrot Mike FM-15 Ranch Rifle 16" 5.56

The Foxtrot Mike Ranch Rifle is the value pick of the IL-compliant 5.56 field. FM Products designed it around a bufferless AR upper paired with a proprietary lower that mounts Remington 870 shotgun stocks directly, eliminating both the buffer tube and the AR pistol grip in one move. The result is an AR-pattern rifle that runs STANAG magazines, accepts any AR-15 trigger group, and clears every PICA, California, and New York feature test without a fixed magazine or a top-loading workaround.

The 16-inch 4150 steel barrel runs a .223 Wylde chamber, 1:8 twist, and a mid-length gas system, with a choice of a crowned non-threaded muzzle or a 1/2x28 threaded muzzle with a 4-port muzzle brake. The upper and lower receivers are mil-spec Type 3 anodized aluminum, and the 15-inch M-LOK handguard provides standard accessory mounting. Stock options at the $999 price point ship a Magpul SGA; upgrade to a WOOX Gladiatore wood stock for $1,199.

For Illinois buyers who want the AR-15 manual of arms, a real adjustable gas system, and pricing under $1,000, the FM-15 Ranch is the cleanest entry point. The trade-off vs the CMMG Dissent or SIG MCX Regulator is the smaller manufacturer aftermarket footprint, though FM Products itself sells direct and has been shipping the platform in volume since 2024.
