Mossberg’s 590S Optics Ready Pump Shotguns

MSRP is $704 wether you choose the 18-5-inch corncob model or the M-LOK equipped 20-inch choked version.

From Mossberg . . .

The flexibility of the 590S Series of 12–gauge shotguns has been enhanced with the addition of two optic–ready versions. Available with 20–inch and 18.5–inch barrel lengths, these pump–actions are capable of cycling 1.75, 2.75 and 3–inch shotshells interchangeably without the use of an adaptor; and now, you can directly mount a low–profile, micro–dot sight to the receiver.

Mossberg 590 tactical shotguns feature non–binding twin action bars; positive steel–to–steel lock–up and anti–jam elevator; dual extractors; drilled and tapped receivers; ambidextrous top–mounted safety; and convenient clean– out magazine tube with cap for ease of maintenance. Standard features of the optic–ready 590S series include black synthetic stock and forend; cylinder bore barrel (AccuChoke™–compatible barrel on the 20–inch version); matte blue metal finish; sling swivel studs; and logo–engraved receiver.

Key design elements of the 590S platform include a redesigned elevator and bolt slide combined with the addition of an energy–absorbing bumper. This patent–pending design allows the user to load their choice of shotshell length (1.75, 2.75 and 3–inch) and shotshell type in any combination. And use of shorter shell lengths will also
increase the overall capacity of the 590S.

590S Optic–Ready Pump–Action Shotguns (51604/51605) – Available with choice of 18.5–inch cylinder bore barrel, featuring a front bead sight and corncob forend or a 20–inch version with AccuChoke–compatible barrel (Cylinder choke tube included), front bead sight, and versatile M–LOK® compatible forend. Both models feature receiver cuts to accept the direct mounting of micro–dot sights (Shield RMSc footprint) and a cover plate is included for use when a sight is not mounted. MSRP: $704
