Mossberg 590A1 12 Gauge Pump, 18.5 in Heavy-Walled Barrel, 6+1 Capacity, Retrograde-Style Wood Furniture
This Mossberg M590A1 stands out with a non-catalog Retrograde-style setup, factory markings, and a purpose-built defensive configuration. It is now fitted with wood furniture, including a corncob forend and checkered buttstock with a ventilated recoil pad, giving it the classic look while retaining the 590A1 heavy-duty build. Per the original box label (SKU 50766), this shotgun left the factory with synthetic furniture and a 7-shot, M-LOK forend; the current Retrograde-style wood furniture was installed after it left the factory. The 18.5 in heavy-walled, cylinder-bore barrel, extended magazine tube, and a hard-anodized receiver in a matching matte gray tone complete a durable and practical package.

The heart of this shotgun is its 18.5 in steel, heavy-walled, cylinder-bore barrel paired with an extended magazine tube for a 6+1 capacity. A barrel and magazine clamp adds rigidity to the front end. The receiver is hard-anodized aluminum in a matte gray tone to match the parkerized steel components and is drilled and tapped with four filler screws installed; no rail is included.
The Retrograde-style wood furniture defines this build. It features a wood corncob forend and a wood buttstock with checkering, a right-hand palm swell, and a ventilated recoil pad. Length of pull is 13.75 in, offering a solid, traditional shoulder fit and controlled handling.
Sighting is straightforward with a brass bead front sight and no rear sight. Controls include Mossberg's tang safety. This model continues the heavy-duty 590A1 lineage with metal trigger guard and safety components.
Chambered for both 2 3/4 and 3 in shells, it is marked on the receiver as M590A1 and on the barrel as 12 GA, 18.5 in. It does not include a heat shield or bayonet lug, keeping the configuration clean and focused on function. Made in the United States with parkerized steel components and a hard-anodized receiver, plus stained wood furniture, this setup blends durability with a classic look.
Overall, this Mossberg M590A1 is a non-catalog configuration fitted with wood furniture, making the shotgun Retrograde style while preserving the robust features that define the 590A1 series.
