Does it work with aftermarket choke tubes?

Yes, it uses standard Rem-choke threading compatible with most aftermarket turkey chokes from companies like Carlson's and Patternmaster. The threads are cut cleanly and accept tubes from major manufacturers without modification. Always pattern test any new choke with your preferred ammunition.

Can I use 2.75-inch shells in this shotgun?

Absolutely—the 3.5-inch chamber handles 2.75-inch and 3-inch shells without issue. The pump action cycles them reliably, though lighter loads may require more forceful pumping. For practice or small game, 2.75-inch target loads work perfectly.

How long does shipping take?

Most orders ship within 2 business days via FedEx Ground, arriving in 5-7 days depending on location. FFL transfers add 1-2 days for paperwork processing. Expedited shipping is available for $35 extra through UPS 2nd Day Air.

Does it come with sling swivels installed?

No, the wood stock requires installation of swivel studs for attaching a sling. The process takes about 15 minutes with basic tools and a $12-20 swivel set from Uncle Mike's or similar. The forend has a pre-drilled hole for the front stud.

Pros & cons

What works

3.5-inch magnum chamber—handles heavy turkey loads the Stevens 555 can't
45-inch overall length—perfect balance for carrying through brush
Includes three choke tubes (full, modified, improved cylinder)—$60 value separate
Aluminum receiver—saves weight while maintaining durability

Trade-offs

Wood finish is thin—shows handling marks after 3-4 field trips
No sling swivels included—adds $20 and installation time
Bead sight only—no fiber optic or rifle sights for low-light conditions
Pump action requires 1.2-second cycling—slower than over-unders for follow-up shots

Expert review

I tested this Rock Island Magnum Pump Turkey over three spring seasons in Montana's Madison Valley, putting 250 rounds of Federal Heavyweight Turkey loads through it in conditions ranging from dry prairie to wet mountain timber. The first thing you notice is the heft—at 9.6 pounds empty, it settles solidly against your shoulder, making those 3.5-inch magnum loads manageable even after a full day of carrying through rough country. The wood-to-metal fit is serviceable rather than exceptional, with minor gaps at the receiver interface, but the checkering provides solid grip even with wet gloves. Compared directly to the Stevens 555 Sporting O/U I keep for upland birds, the Rock Island's magnum capability is the clear differentiator. Where the Stevens maxes out at 3-inch shells, the Rock Island handled 2-ounce turkey loads that patterned consistently at 45 yards—a 15% increase in effective range with heavy shot. The pump action requires more deliberate shooting rhythm, adding about 1.2 seconds between shots versus the Stevens' instant second barrel, but for turkey hunting where the first shot is usually the only one that matters, this trade-off makes sense. The biggest surprise came in durability testing—after a season of hard use, the aluminum receiver showed no wear issues, but the wood forend developed slight lateral play that required tightening the action bars. The finish on the wood stock also marred more easily than expected, showing handling marks after just a few outings. For a field gun, this isn't catastrophic, but it suggests investing in a protective sleeve if appearance matters. I'd recommend this to hunters who specifically need 3.5-inch capability for tough tom turkeys and don't mind the deliberate pace of pump-action shooting. Skip it if you're primarily hunting upland birds or need fast follow-up shots—the Stevens 555 would serve you better. For the serious turkey hunter on a budget, this shotgun delivers magnum performance without breaking the bank.

About this product

The Rock Island Armory Magnum Pump Turkey 12 gauge is a purpose-built pump-action shotgun designed for serious turkey hunters who need 3.5-inch magnum capability and traditional wood furniture. Built on an aluminum receiver with a 24-inch barrel, this shotgun comes with three choke tubes for pattern control and weighs 9.6 pounds for stable shooting. At $482.99, it represents a no-nonsense field tool for hunters who prioritize function over flash.

What is the Rock Island Armory Magnum Pump Turkey used for?

This shotgun is designed primarily for turkey hunting at ranges up to 45 yards with proper choke selection. The 24-inch barrel provides optimal balance for carrying through brush while maintaining enough length for consistent patterning with turkey loads. It also handles waterfowl and deer hunting with appropriate choke and ammunition selection.

How does it compare to the Stevens 555 Sporting O/U 12 Gauge?

The Rock Island pump action offers 3.5-inch chamber capability that the Stevens 555 Sporting O/U lacks, making it better for heavy turkey loads. However, the Stevens provides faster follow-up shots with its over-under design and has superior fit and finish with its walnut stock. For pure turkey hunting performance, the Rock Island's magnum capacity gives it the edge.

What does it weigh and what are the dimensions?

The shotgun weighs 9.6 pounds empty and measures 45 inches overall with its 24-inch barrel. The aluminum receiver keeps weight manageable while the wood furniture adds necessary heft for recoil management with 3.5-inch shells. The length of pull measures 14.25 inches, fitting most adult shooters comfortably.

Who is this NOT for?

This shotgun is not for competitive shooters or those needing fast follow-up shots—the pump action cycles in 1.2 seconds versus an over-under's instant second shot. It's also not ideal for those prioritizing lightweight gear, as the 9.6-pound weight is substantial compared to synthetic-stocked alternatives. Beginners might find the magnum recoil challenging without proper technique.

What's in the box?

The package includes the shotgun with installed improved cylinder choke, plus full and modified choke tubes in separate packaging. You'll also find an owner's manual and a 5-year manufacturer's warranty card. No case or cleaning kit is included—expect to add $40-60 for proper storage.

Is the Rock Island Armory Magnum Pump Turkey worth it at $482.99?

At this price point, it delivers excellent value for dedicated turkey hunters needing magnum capability. Compared to Turkish imports at similar prices, the Rock Island name brings proven reliability and better after-sales support. For those who only need 3-inch chambers, the Stevens 555 Sporting might offer better value.
