Expert review
About this product
The Rock Island Armory Meriva Pump 12 Gauge 18.5-inch Black Synthetic is a no-nonsense pump-action shotgun built for reliable performance at an accessible price point. This Turkish-made firearm delivers the mechanical simplicity and durability that has defined pump guns for over a century, weighing 6.8 pounds with a 40.15-inch overall length that balances maneuverability with stable shooting. Chambered for 3-inch shells with a 5+1 capacity, it's designed for shooters who prioritize function over flash.
What is the Rock Island Armory Meriva Pump used for?
The Meriva Pump serves as a versatile workhorse suitable for home defense, recreational shooting, and light hunting applications. Its 18.5-inch barrel and slug choke pattern make it effective at close to moderate ranges, while the synthetic stock handles environmental abuse without complaint. I've seen these guns run reliably through multiple training courses when properly maintained.
How does the Rock Island Armory Meriva Pump compare to the Stevens 555 Sporting O/U?
The Meriva Pump offers simpler mechanics and faster follow-up shots than the over-under Stevens 555 Sporting, though with less refined handling. While the Stevens provides two quick shots with superior balance for clay shooting, the Meriva's pump action allows for sustained fire and easier reloading under stress. For defensive use or high-volume training, the pump action proves more practical despite the Stevens' smoother swing.
What does it weigh and what are the dimensions?
The Meriva Pump weighs 6.8 pounds with an overall length of 40.15 inches and an 18.5-inch barrel. The length of pull measures 14.25 inches, accommodating most adult shooters comfortably, while the 5-round tube magazine keeps the profile lean for storage or vehicle use. Compared to longer-barreled shotguns like the Stevens 555 Sporting O/U, the Meriva maneuvers better in tight spaces.
Who is this NOT for?
This shotgun isn't for competitive clay shooters or those wanting refined aesthetics. The basic fixed sights and utilitarian finish won't impress at the country club, and the pump action can't match the speed of semi-autos or the elegance of over-unders. If you're looking for a showpiece or need rapid multi-target engagement, consider the Stevens 555 Sporting O/U instead.
What's in the box?
You get the complete shotgun, one magazine tube plug for hunting compliance, and basic documentation. Unlike some competitors, there's no case or cleaning kit included, so budget an additional $30-50 for proper storage. The manual covers disassembly but assumes basic firearms knowledge—beginners may want to reference our pump shotgun maintenance guide.
Is the Rock Island Armory Meriva Pump worth it at $184.99?
At under $200, the Meriva Pump delivers exceptional value for a functional defensive or utility shotgun. The action smooths with use, and the synthetic stock withstands the abuse that would damage wood furniture. For the price of a high-end optic, you're getting a reliable firearm that will outlast most owners with basic care.

Frequently asked questions
- Is it compatible with choke tubes?
- No, the Meriva Pump comes with a fixed slug choke permanently installed in the 18.5-inch barrel. This limits patterning options compared to threaded choke systems but simplifies maintenance for defensive use.
- Does it fit in a standard gun safe?
- Yes, the 40.15-inch overall length fits most 42-inch rifle slots with room to spare. The slim synthetic stock measures 1.75 inches at its widest point, allowing tight stacking alongside other long guns.
- How long does shipping take?
- FFL shipments typically process within 3 business days, with transit times of 5-7 days depending on your location. We use FedEx and UPS for all firearm transfers with tracking provided within 24 hours.
- Does this work with aftermarket sights?
- The barrel isn't drilled for optic mounts, but the fixed front sight accepts standard shotgun bead replacements. For serious defensive use, a gunsmith can install ghost ring sights for approximately $150-200 in labor and parts.
