Mossberg Model 200K-A 12 Gauge Pump-Action Shotgun, 28" Ported Barrel, Variable Choke
Offered here is a Mossberg Model 200K-A, the scarce follow-up revision to Mossberg’s first pump-action shotgun produced only from 1955 to 1956. Known for its detachable box-magazine design, enclosed slide mechanism, and factory “C-Lect” variable choke, this full-size 12-gauge makes a notable addition for collectors seeking an early, limited-production Mossberg pump.

What’s Included

The 200K-A’s enclosed steel handguard and slide assembly protect the action bars while giving the forend a distinctive, streamlined profile. This design was unique to the 200K series and is rarely seen on later Mossberg pumps.
A factory-installed, ported 28-inch barrel features the adjustable “C-Lect” choke system, allowing the shooter to dial in patterns from cylinder to full without changing tubes. Barrel markings confirm “MODEL 200K A 12 GA 2 ¾ INCH.”
Controls remain familiar to Mossberg users, with a tang-mounted two-position safety and a robust steel receiver finished in blued carbon steel. Sighting is straightforward thanks to a brass bead up front paired with a drift-adjustable rear notch.
The walnut stock wears a pistol-grip wrist and ventilated recoil pad for comfortable shouldering. A 13.5-inch length of pull suits most adult shooters while retaining the original mid-century look and feel.
Because production of the 200K-A lasted only two years, complete examples are increasingly scarce. This shotgun presents a solid shooting platform and a tangible link to Mossberg’s entry into pump-action design.
