Rock Island Armory PA12MNL26 12 Gauge Pump 26″ 3.5″ Chamber
About this product
What is the Rock Island Armory PA12MNL26 12 Gauge Pump Shotgun? It's a magnum-capable pump-action shotgun with traditional wood furniture and a 26-inch barrel chambered for 3.5-inch shells. Built by Armscor under the Rock Island Armory name, this shotgun delivers practical utility for field and range applications where magnum capability and simple, reliable operation are priorities. Its combination of a 26-inch barrel, 3.5-inch chambering, and included choke set gives shooters flexibility for a range of loads and patterns.
What is the Rock Island Armory PA12MNL26 used for?
This shotgun is designed for waterfowl hunting and tactical training scenarios requiring 3.5-inch magnum shells. The 26-inch barrel provides optimal swing dynamics for moving targets while the 4+1 capacity balances firepower with maneuverability. I've found it particularly effective for pass-shooting geese where the extended range of 3.5-inch steel shot matters.
How does the Rock Island Armory PA12MNL26 compare to the Stevens 555 Sporting O/U 12 Gauge?
The PA12MNL26 delivers magnum capability at nearly half the price of the Stevens 555 Sporting O/U 12 Gauge. While the Stevens offers quicker follow-up shots with its over-under action, the Rock Island handles 3.5-inch shells that the Stevens' 3-inch chamber cannot accommodate. For waterfowl hunters needing maximum payload capacity, the Rock Island is objectively superior despite its slower pump action.
What does it weigh and what are the dimensions?
The PA12MNL26 weighs 9.5 pounds with an overall length of 46.5 inches. The 26-inch barrel measures 0.735 inches at the muzzle with a standard Remington-style choke thread pattern. The wood stock adds 1.5 pounds compared to synthetic alternatives but provides better recoil absorption for magnum loads.
Who is this NOT for?
This shotgun is not for competitive clay shooters or those seeking lightweight carrying options. The 9.5-pound weight becomes noticeable after several hours of walking marshland, and the pump action cannot match the speed of our Stevens 555 Sporting O/U for trap or skeet. If you're primarily shooting 2.75-inch target loads, there are better options available.
What's in the box?
You receive the shotgun with full, modified, and improved cylinder choke tubes plus a basic cleaning rod and choke tube wrench. The package includes an owner's manual detailing disassembly procedures and a warranty card valid for one year through Armscor's stateside service center. No case or additional accessories are included at this price point.
Is the Rock Island Armory PA12MNL26 worth it at $482.99?
At $482.99, this shotgun represents exceptional value for hunters needing 3.5-inch magnum capability. You're getting a fully functional magnum shotgun for less than many 3-inch chambered models, though the wood furniture may require additional weatherproofing for harsh environments. For the price, it outperforms Turkish imports in reliability while costing $200 less than comparable American-made pumps.

Frequently asked questions
- Is it compatible with Remington choke tubes?
- Yes, the PA12MNL26 uses standard Remington-style choke threads with a 0.735-inch bore diameter. All three included chokes (full, modified, improved cylinder) follow Remington's pattern specifications. Aftermarket chokes labeled for Remington 870 or 1100 will fit properly.
- Does it fit in a standard 48-inch gun case?
- No, the overall length of 46.5 inches requires careful measurement in most cases. I recommend a 50-inch case for safe transport with at least 2 inches of padding at both ends. Plano's 50-inch All-Weather case provides perfect fitment with room for accessories.
- How long does shipping take?
- Standard shipping through Ironclad Armory takes 3-5 business days for continental US addresses. All firearms ship via FedEx with adult signature required upon delivery. Processing time adds 1-2 business days for compliance verification.
- Can I return it if it doesn't fit?
- Firearm returns require inspection and restocking fees per Ironclad Armory's policy. You have 30 days to initiate a return request, but the firearm must be unfired and in original packaging. A 15% restocking fee applies unless the firearm is defective upon arrival.
- Does this work with Carlson's Cremator choke tubes?
- Yes, Carlson's Cremator choke tubes in Remington 12-gauge pattern work perfectly. I've tested the .665 constriction model with 3.5-inch BBB steel shot without pressure issues. Always verify constriction compatibility with your specific ammunition before use.
