Built on Remington’s solid-steel 870 action, this TAC-14 carries the RF-prefix serial number that identifies late Ilion, NY manufacture. The receiver is drilled and tapped for optics, with factory plugs installed, giving the buyer an easy upgrade path.
Mesa Tactical’s LEO Gen II adapter mates the shotgun receiver to an AR-15 carbine receiver extension, opening up a wide range of aftermarket stock and brace options. The included SB Tactical SOB arm brace provides an adjustable length of pull while keeping the firearm’s overall length NFA-compliant.
The 14" cylinder-bore barrel wears a plain bead front sight and a durable matte black oxide finish. It feeds from a 4-round magazine tube for a 4+1 total capacity and chambers both 2¾" and 3" shells without modification.
Magpul’s MOE 870 fore-end adds molded-in M-Lok slots for lights or other accessories, enhancing control and customization without extra weight. A cross-bolt safety, smooth pump action, and common 870 pattern parts round out a configuration that balances maneuverability with familiar 870 reliability.
