Armscor Meriva Rocki CR103 12 Gauge 18.5" Pump Action Shotgun - Black

The Armscor Meriva Rocki CR103 12 gauge pump action shotgun delivers straightforward reliability in a compact, no-nonsense package. Built on the proven CR103 platform, this 18.5-inch barrel shotgun is engineered for home defense, tactical training, and close-quarters work where maneuverability matters. The 3-inch chamber handles both 2.75-inch and 3-inch shells, giving you flexibility in ammunition choice, while the 5+1 capacity provides a fighting load without excessive length. Rock Island Armory's reputation for honest, durable firearms comes through in every detail here—there's no marketing fluff, just a hard-working shotgun that handles the job.

The 18.5-inch barrel strikes the balance every defensive shotgun should: short enough to slice through doorways and tight spaces, long enough to generate velocity and pattern consistency out to typical engagement distances. A polymer stock keeps weight down and resists the weather, while the flash suppressor helps manage muzzle signature in low-light encounters. This is a shotgun built for the person who wants a capable, affordable defensive tool without paying for features they'll never use.

Whether you're setting up a home-defense battery, training for tactical courses, or simply adding a reliable pump gun to your safe, the CR103 delivers proven mechanics at a price that makes sense. Rock Island Armory shotguns have earned their place in working arsenals across the country—this one carries on that tradition.

The CR103 is chambered in 12 gauge with a 3-inch chamber. It will safely fire both 2.75-inch and 3-inch shotshells, giving you options on ammunition type, shot size, and brand.

Is this shotgun suitable for home defense?

Yes. The 18.5-inch barrel, pump action, and 5+1 capacity make it well-suited for defensive use. The flash suppressor helps manage muzzle blast in enclosed spaces, and the compact length makes it easier to maneuver in tight hallways and rooms compared to longer sporting shotguns.

What comes with the shotgun?

You receive the CR103 shotgun as configured. Refer to the product documentation or contact us for information on any included accessories or documentation.

How does the pump action work?

The slide (pump handle) beneath the barrel cycles the action. Pull it back after each shot to eject the spent shell and chamber the next round from the magazine tube. It's a simple, proven system used by law enforcement and home defenders for over a century.
