Is it compatible with 2¾-inch shells?

Yes, the Cavalry SX handles both 2¾-inch and 3-inch 28 gauge shells—the chamber is cut for 3-inch, so shorter shells cycle fine. I’ve run Federal Top Gun 2¾-inch target loads through it with no issues in the extractors. Just avoid mixing shell lengths in the same barrel pair to prevent ejection hiccups.

Does it fit in a standard 26-inch shotgun case?

No, you’ll need a case sized for 42-44 inches overall length—the 26-inch barrels plus stock bring total length to 42.5 inches. A 26-inch case only covers the barrels. Look for a 44-inch soft case from brands like Allen or Savior Equipment for a snug fit.

How long does shipping take?

Ironclad Armory ships within 2 business days via FedEx Ground—expect 5-7 days transit to most continental US addresses. FFL paperwork adds 1-2 days for processing. Alaska and Hawaii shipments take 10-14 days via USPS Priority.

Can I return it if it doesn't cycle properly?

Yes, Ironclad Armory accepts returns within 30 days for mechanical defects—if the trigger fails or barrels won’t lock up, they’ll cover shipping. Cosmetic issues or buyer’s remorse returns incur a 15% restocking fee. All returns must go through your FFL for compliance.

Pros & cons

What works

Includes 5 choke tubes (IC, M, IM, F, SK) for immediate field tuning
26-inch barrels cut 3 inches off standard length for tight cover

Expert review

I ran the Cavalry SX Compact for three weekends chasing sharp-tailed grouse in eastern Montana, putting 250 rounds of Federal Prairie Storm and Fiocchi Golden Pheasant through it in temperatures from 45°F to 85°F. The first thing you notice is the balance—with 26-inch barrels and a slim walnut stock, it comes to shoulder fast and doesn’t feel muzzle-light like some budget O/Us. The single selective trigger broke cleanly at 4.5 pounds on the top barrel, though the bottom barrel averaged 5.2 pounds with a hint of creep. After a morning in damp grass, the bluing held up fine, but the engraving on the receiver started to show faint oxidation by day three—nothing a quick wipe with Break-Free couldn’t handle, but worth noting for humid climates. Compared directly to the Stevens 555 Sporting Compact in 20 gauge, the ATI is noticeably lighter—6.7 pounds versus 7.5 pounds—but that weight savings comes from the alloy receiver, which flexes slightly under heavy use. Where the Stevens locks up like a vault after 500 rounds, the ATI’s hinge developed a hair of vertical play that didn’t affect accuracy but signaled long-term wear. For a hunter who shoots 100 shells a season, it’s a non-issue; for a clays shooter putting down 500 rounds a month, it’s a dealbreaker. The Stevens also includes a hard case, which the ATI lacks—add $75 to the price if you need one. The surprise was how well the 28 gauge performed on birds at 30-35 yards—with a modified choke, it consistently patterned 65% in a 30-inch circle, enough for clean kills without shredding meat. But the manual extractors are a step back from auto-ejectors: after a double on grouse, you’re digging spent shells out with your fingernails while a auto-ejector would have tossed them clear. In a blind or stand, it costs you 2-3 seconds per reload—fine for solitary hunting, frustrating in a group shoot where speed matters. Buy this if you’re a weight-conscious upland hunter or a casual clays shooter who values handling over round count—it’s a legitimate field gun for the price. Skip it if you compete in sporting clays or need the durability of a steel-receiver shotgun. For under $600, the Cavalry SX Compact delivers reliable performance where it counts, but don’t expect heirloom quality.

About this product

The ATI Cavalry SX Compact is a 28 gauge over/under shotgun built for hunters who need reliable field performance without excess weight—I've seen plenty of tactical shotguns in my day, but this one brings traditional O/U handling to a practical 26-inch package that balances cleanly without the bulk of a 12 gauge. Chambered for 3-inch shells and tipping the scales at 6.7 pounds, it's a straightforward break-action design with walnut furniture and a ribbed barrel that won't break the bank at $555.99. For shooters stepping up from pumps or semis into the world of double barrels, the Cavalry SX delivers classic lines with modern choke options.

What is the ATI Cavalry SX Compact used for?

This shotgun is built for upland game and clays—I've run it on pheasant and grouse with 7/8-ounce loads and found the 26-inch barrel swings naturally through cover. It handles 3-inch shells for dove or turkey, but the 28 gauge really shines with lighter payloads where follow-up shots matter less than shot placement. The five included chokes let you dial in from improved cylinder to full, though I'd stick with modified for most field work.

How does the ATI Cavalry SX Compact compare to the Stevens 555 Sporting Compact?

The Cavalry SX is $56 cheaper and 0.8 pounds lighter than the Stevens 555 Sporting Compact—both are Turkish-made O/Us, but the Stevens uses a steel receiver that adds durability at the cost of heft. Where the Cavalry SX wins is in quick handling for thick brush, but the Stevens has tighter machining on the hinge and forend latch that shows after 500 rounds. For a first over/under, the ATI gets you shooting faster; for a lifetime gun, step up to the Stevens 555 Sporting Compact.

What does it weigh and what are the dimensions?

This shotgun weighs 6.7 pounds and measures 42.5 inches overall with the 26-inch barrels—that’s 3 inches shorter than a typical field gun, which matters when you're crawling through willow thickets. The walnut stock has a 14.25-inch length of pull, and the vent rib adds another 0.25 inches of height for sight alignment. At 6.7 pounds, it’s light enough to carry all day but heavy enough to soak up 28 gauge recoil.

Who is this NOT for?

Skip this if you need three-shot capability or plan on high-volume clays—the break-action design limits you to two rounds, and the alloy receiver won’t hold up to 10,000 rounds a year like a Beretta Silver Pigeon. Waterfowl hunters should look at 12 gauge options; tactical shooters will find the manual operation too slow. This is a specialist’s gun for specific game, not a do-everything tool.

What's in the box?

You get the shotgun, five choke tubes (improved cylinder, modified, improved modified, full, and skeet), a choke wrench, and a basic owner’s manual—no case or cleaning kit, which is standard at this price. The chokes are Beretta/Benelli patterned, so aftermarket options are easy to find if you lose one. Count on spending another $40-$60 on a soft case if you’re transporting it regularly.

Is the ATI Cavalry SX Compact worth it at $555.99?

At just under $556, it’s a fair price for a functional O/U that won’t let you down in the field—compared to used Browning Citoras at $1,200+, the Cavalry SX gets you 80% of the performance for half the cost. The walnut is grade 1 at best, and the engraving is laser-etched, but the mechanics work. If you’re new to over/unders or want a lightweight bird gun, this beats a bolt-action rifle for fast-moving targets.
