The Mossberg 590M Breacher Professional Series is a magazine-fed pump-action platform developed from a military contract and purpose-built for breaching and close-quarters operations — classified as an Any Other Weapon (AOW) under the NFA requiring a tax stamp, and featuring an 11.5" heavy-walled barrel with a one-piece machined integrated stand-off muzzle device for door breaching applications at just 24.5" overall length and 7 lbs. The double-stack detachable magazine system uses integral stabilizing ribs that engage directly to receiver notches for positive lockup, paired with an all-steel ambidextrous magazine release positioned in front of the trigger guard so it never interferes with cycling — and the compact M-LOK compatible forend allows accessory mounting to sides and bottom without adding unnecessary bulk. Core 590M platform features are fully present: dual extractors, twin non-binding action bars, steel-to-steel lockup, drilled and tapped receiver, oversized ambidextrous top-mounted safety with highly visible red indicator, Mossberg Aftershock bird's head grip for reduced recoil and positive control, and the signature Tungsten Cerakote finish across all metal surfaces — shipping with one 5-round double-stack magazine with 10, 15, and 20-round options available separately.
