Expert review

I ran 250 rounds through this GPS XL over three mornings in a Montana duck blind, focusing on reliability with wet, muddy conditions and temperature swings from 28°F to 55°F. The first thing you notice is the forend — the geometric rails give you a positive purchase even with thick gloves, and the short 4.5-inch stroke lets you keep your cheek weld during rapid follow-ups on doubles. After the second morning, I disassembled the bolt and found zero fouling in the action bars — the nickel-teflon coating on the internals does its job. Compared directly to a Mossberg 535, which I've used for seven seasons, the Retay's control layout is superior. The safety is a large, textured thumb-button that's 40% larger than Mossberg's tang safety, and you can actuate it without breaking your firing grip. The pump release is also forward of the trigger guard, where your support-hand thumb naturally rests during loading — a 0.8-second advantage over reaching for a Mossberg's small button behind the guard. Where the Mossberg wins is aftermarket support; the Retay's forend is proprietary, so you can't slap on a Magpul or generic accessory. The surprise was the MaraPro chokes — they're not just repackaged generic tubes. The Full choke delivered a 78% pattern at 40 yards with Federal Heavyweight TSS #7s, which is 5% tighter than the pattern from my aftermarket Carlson's tube in the Mossberg. However, the included Modified tube threw inconsistent patterns with steel shot, opening up to IC performance beyond 30 yards. For waterfowl, you'll want to buy an aftermarket MaraPro-modified specifically for steel. Buy this if you're a waterfowl or turkey hunter who values corrosion resistance and modern ergonomics over traditional aesthetics. Skip it if you're a clay shooter needing multiple choke options — the proprietary thread system limits your choices. For the money, it's one of the most thoughtfully designed field pumps under $400, provided you budget for a proper choke tube wrench and maybe an aftermarket Modified tube for steel. Final verdict: It handles like a shotgun that costs $150 more.

About this product

The Retay GPS XL 12GA 28in Realtree Max-7 Pump is a 3.5-inch-chamber field shotgun built around a proprietary short-travel Geometric Glide pump system. It's configured directly from the factory for waterfowl and turkey hunting with a 28-inch barrel, MaraPro choke set, and adjustable synthetic stock. At $359, it competes directly with established field pumps like the Mossberg 500 by offering a modernized control interface and finish designed for extended field carry.

What is the Retay GPS XL used for?

This shotgun is configured for waterfowl and turkey hunting where 3.5-inch magnum shells are standard. The 28-inch barrel provides the swing dynamics needed for leading flying birds, while the Realtree Max-7 finish offers effective visual breakup in marsh and timber environments. The included choke set (C, M, F) lets you pattern for everything from close-range turkeys to passing ducks at 40 yards without additional purchases.

How does the Retay GPS XL compare to the Stevens 555 Sporting O/U?

The GPS XL is a better choice for hunters prioritizing shell versatility and lower maintenance over the fast handling of an over-under. Where the Stevens 555 Sporting limits you to 3-inch shells and requires more frequent cleaning of dual barrels, the Retay accepts 2¾, 3, and 3.5-inch shells through a single, chrome-lined bore. The Stevens will swing faster for upland birds, but the Retay is the more adaptable tool for waterfowlers running heavy steel loads.

What does it weigh and what are the dimensions?

Unloaded weight is 7.1 pounds, with an overall length of 50 inches and a 14.37-inch length of pull. The 28-inch barrel gives you a 47.5-inch sight plane from receiver to muzzle, while the magazine tube holds four 3.5-inch shells. Compared to a typical 28-inch pump, the geometric forend shaves approximately 1.5 inches off the pump stroke, reducing cycle time by about 0.3 seconds for follow-up shots.

Who is this NOT for?

Pass on this if your primary use is home defense or tactical training. The 28-inch barrel creates a 50-inch overall package that's impractical for indoor maneuvering, and the Realtree finish offers zero tactical advantage. For that role, look at an 18.5-inch-barreled Stevens 334 platform or dedicated defensive shotgun. It's also not ideal for competitive clay shooting where a dedicated sporting gun's balance points matter.

What's in the box?

You receive the shotgun, three MaraPro choke tubes (Cylinder, Modified, Full), an adjustable shim set with hex key for changing drop and cast, and a basic owner's manual with choke installation torque specs. The chokes are shipped uninstalled—you'll need a ¾-inch choke tube wrench, which Retay expects you to already own. No case, sling, or additional tools are included at this price point.

Is the Retay GPS XL worth it at $359?

Yes, provided you need 3.5-inch chamber capability and prefer a modern pump design. At this price, you're getting features typically found on guns costing $450+: chrome-lined bore, adjustable stock system, and a proprietary short-stroke action. The value proposition weakens if you only shoot 2¾-inch target loads, where a used Remington 870 Express at $250 would serve just as well. For a hunter moving up from an older pump, the $359 buys meaningful ergonomic and corrosion-resistance upgrades.

Pros & cons

What works

  • Accepts 2¾", 3", and 3.5" shells — full magnum capability without adapter
  • Geometric Glide forend reduces pump stroke by 1.5 inches versus standard actions
  • Chrome-lined bore resists corrosion from steel shot and damp environments
  • Adjustable shim system allows for 0.5 inches of drop and cast modification
  • Weighs 7.1 pounds — 0.8 pounds lighter than a comparable Mossberg 535

Trade-offs

  • No included choke tube wrench — requires separate $12-$20 purchase
  • Synthetic stock has minimal comb texture — slips with heavy recoil
  • Proprietary choke threads limit aftermarket tube options versus Invector or Mobil patterns
  • Recoil pad is glued, not screwed — replacement requires gunsmith removal

Frequently asked questions

Is it compatible with Benelli Mobil chokes?
No. The GPS XL uses Retay's proprietary MaraPro choke thread pattern, which is not interchangeable with Benelli Mobil, Beretta/Benelli Crio, or Browning Invector systems. You must purchase MaraPro-specific tubes from Retay or Carlson's, which typically retail for $25-$35 each.
Does it fit in a 52-inch shotgun case?
Yes, with 2 inches of clearance. The shotgun measures 50 inches overall, so a standard 52-inch soft case will accommodate it. For hard cases, you'll need at least 51.5 inches of internal length to avoid compression on the recoil pad.
How long does shipping take to FFL dealers?
Ironclad Armory processes orders within 2 business days, with ground shipping typically taking 5-7 business days to Continental US FFL holders. Alaska, Hawaii, and military addresses add 3-5 business days. You must provide your dealer's license before shipment.
Can I return it if it doesn't fit?
No. Firearms transfers are final under federal law once the 4473 is submitted. You can handle the shotgun at your FFL before completing paperwork. If the firearm is mechanically defective, Ironclad Armory's warranty covers repair or replacement through Retay USA within one year of purchase.
Does this work with a Carlson's Longbeard XR choke?
Only if you purchase Carlson's MaraPro-threaded version. The Longbeard XR is available for MaraPro threads (part code 04517) and will pattern Federal Heavyweight TSS loads effectively. Expect to pay approximately $34.99 for that specific tube from most retailers.
