Description
There's something right about a pump gun with real wood on it, and the Rock Island Armory PA12 Waterfowl leans into that old-school appeal while packing modern magnum capability. The 3.5" chamber is the headline here. Plenty of budget-friendly pumps top out at 3" shells, but this one runs the full range from light 2.75" target loads up to heavy 3.5" magnum steel, which is exactly what you want when geese are working the decoys at the edge of your effective range.
Built for the Blind: PA12MNL26 Details
The 26" barrel wears a ventilated rib with a bead front sight, a proven setup for swinging on passing birds. It's threaded for choke tubes and ships with Full, Modified, and Improved Cylinder chokes, so you can tighten up for pass shooting or open things up for close work over decoys without buying anything extra. The receiver is aluminum with a black anodized finish, which helps keep the overall weight to a manageable 7.6 pounds even with the wood furniture. Capacity is 4+1, and the whole package measures 46.2" from butt to muzzle.
Why the Rock Island PA12 Makes Sense
Armscor has built a reputation on delivering working guns at working prices, and the PA12 follows that same playbook. The pump action is about as simple and dependable as shotgun designs get, with no gas system to clean or tune and no fussiness about shell length or load weight. Cold mornings, wet blinds, and muddy boat rides are just part of the job for a gun like this. Rock Island also backs its firearms with a limited lifetime warranty, which is a nice bit of peace of mind on a hard-use hunting gun.
Rock Island Armory PA12MNL26 in the Field
With the walnut stock and forend, this shotgun looks the part in a duck boat or walking a fencerow for pheasants, and the 3.5" chamber means it can pull double duty as a turkey gun with the right choke and load. If you want one shotgun that covers waterfowl season and then some, this one earns its spot in the safe.

Frequently Asked Questions
Can the Rock Island PA12 Waterfowl shoot 2.75" and 3" shells, or only 3.5" magnums?
It handles all three. The 3.5" chamber is the maximum shell length, and because it's a pump action, it will cycle 2.75", 3", and 3.5" shells without any adjustment. That makes it easy to run cheap target loads for practice and step up to heavy magnum steel when the season opens.
What choke tubes come with the PA12MNL26?
It ships with three tubes: Full, Modified, and Improved Cylinder. That trio covers most hunting situations, from tight patterns for pass shooting to more open spreads for birds over decoys. The barrel is threaded, so you can add specialty chokes down the road if you want.
Is the PA12 Waterfowl a good choice for turkey or upland hunting too?
It works well beyond the duck blind. The 3.5" chamber and included Full choke make it capable on turkeys, and the 26" barrel with a bead sight swings nicely on upland birds like pheasant and quail. It's a versatile all-around hunting pump, not just a waterfowl gun.
Does Rock Island Armory back the PA12MNL26 with a warranty?
Yes. Rock Island Armory offers a limited lifetime warranty on its firearms for their intended use. Registering the shotgun with the manufacturer after purchase activates the coverage.
