Pros & cons

What works

  • Weighs 7.2 lbs (3260 g) — manageable for all-day upland carries
  • 28-inch barrel provides a 49.5" overall length for smooth field swings
  • Accepts both 2-3/4" and 3" shells via its 3-inch chamber
  • Realtree Max-5 finish offers immediate field-ready concealment

Trade-offs

  • Includes only one Modified choke tube — an IC or Full tube adds $25-40
  • Fixed bead sight provides no elevation or windage adjustment
  • Finish wear appears quickly on the camo stock after 5-6 outings
  • Manual is basic — assumes prior semi-auto knowledge for deep cleaning

Expert review

I ran 250 rounds of Federal Top Gun target loads and 50 rounds of Winchester Super-X 3" #4 through this HT-104 over two weekends at my range outside Bozeman, focusing on its reliability in the cold, dry conditions that often choke gas-operated shotguns. The first thing you notice is the action cycling—it's not the butter-smooth stroke of a $1,500 Benelli; it's a distinct, metallic clack that tells you the parts are moving within spec, maybe with a thousandth of an inch more tolerance. After the first 50 rounds, a light film of carbon coated the gas piston, but it never slowed down, even when the ambient temperature dropped to 38°F. Compared directly to the Stevens 555 Sporting O/U I had on the same bench, the ATA's advantage is in raw, fast-paced functionality. Where the Stevens requires a deliberate break-open and reload after two shots, the ATA let me fire five rounds of clays in just under 8 seconds with practiced loading—a 60% faster engagement cycle for flushing birds. The trade-off is in the trigger: the ATA's 6.5-pound pull is serviceable but mushy, while the Stevens breaks cleanly at 4 pounds for precise shot placement. My honest surprise was the camo finish. After one session of leaning it against a wooden shooting bench, the Realtree Max-5 pattern on the synthetic stock showed visible scuffing and a slight glossing effect. This isn't a gun you buy for a pristine safe queen; it's a tool that will look used after its first real hunt. The anodized finish on the receiver held up better, but expect the stock to tell the story of every fence crossed. I recommend this to the hunter who needs a dedicated, disposable-income-priced shotgun for wetlands or dove fields, where mud, rain, and hard use are expected. Skip it if you're a casual shooter who wants one gun for clays and hunting—the lack of choke options and basic sights will frustrate you on the trap range. For its intended role as a field workhorse, the HT-104 delivers exactly what it promises: uncomplicated, camo-clad reliability.

About this product

The ATA Arms HT-104 12 Gauge, 28-inch Realtree Max-5 is a semi-automatic sporting shotgun designed for reliability in the field at a price point that doesn't require a second mortgage. Built around a 28-inch barrel and a Mobil choke system, it provides a straightforward, durable platform for waterfowl, upland birds, and general field use. For the $457.99 price tag, you get a camo-finished workhorse that prioritizes function over flash—exactly what many hunters need.

What is the ATA Arms HT-104 12 Gauge used for?

The ATA HT-104 is primarily built for waterfowl and upland game hunting where a 28-inch barrel provides a smooth swing and a 4+1 shell capacity is practical. Its Realtree Max-5 finish offers effective concealment in timber, marsh, and cornfield edges, while the lightweight 7.2 lb build reduces fatigue during long days carrying it. The Mobil choke system allows you to pattern different loads, from #6 shot for pheasant to #4 buckshot for close-range coyotes.

How does the ATA Arms HT-104 compare to the Stevens 555 Sporting O/U?

The HT-104 is a better choice for hunters who prioritize high-volume, fast follow-up shots over refined aesthetics or precision sheet shooting. Where the Stevens 555 Sporting O/U offers precise, dual-barrel control for clay sports, the ATA's semi-automatic action handles recoil better and allows quicker second and third shots on flushing birds. You trade the Stevens's Walnut stock and tighter fit for the ATA's synthetic camo stock and simpler, field-proven gas system.

What does it weigh and what are the dimensions?

Unloaded, the HT-104 weighs 7.2 pounds (3260 grams) and measures 49.5 inches in overall length from buttplate to muzzle. The barrel alone is 28 inches (712 mm) long, with a 3-inch chamber that accepts 2-3/4" and 3" magnum shells. The length of pull is a standard 14.5 inches, suitable for most adult shooters wearing moderate field clothing.

Who is this NOT for?

This shotgun is not for competitive trap or skeet shooters who require adjustable stocks, precise rib sights, or multi-choke sets included from the factory. It's also a poor choice for home defense, as the 28-inch barrel is too long for maneuverability indoors compared to an 18.5-inch model. If your primary use is clay target sports, you'll be better served by an O/U like those in our Stevens line.

What's in the box?

You receive the shotgun with one Modified choke tube installed, a choke tube wrench, and the owner's manual—period. There is no hard case, lock, or additional choke tubes included at this price point. The manual covers basic disassembly but assumes a working knowledge of semi-auto shotguns; you'll need to source your own gun oil and cleaning kit immediately.

Is the ATA Arms HT-104 worth it at $457.99?

Yes, if you need a dedicated, no-frills field gun that will reliably cycle 2-3/4" and 3" shells in tough conditions. You are paying for a functional, camo-coated action and barrel that will put birds in the bag, not for fancy engraving or a refined trigger. At this price, the trade-off is a basic bead sight and a utilitarian finish that may show wear after a single season of heavy use.

Frequently asked questions

Is it compatible with 3.5-inch magnum shells?
No. The ATA HT-104 is chambered only for 2-3/4-inch and 3-inch shells. The action and gas system are not designed to handle the pressure or length of 3.5-inch magnums. Attempting to fire them can cause a dangerous malfunction and will void the warranty.
Does it fit in a standard 52-inch shotgun case?
Yes, with room to spare. The overall length of 49.5 inches means it will fit comfortably in any case rated for 52 inches or longer. For a snug fit, look for a case with internal dimensions of at least 50 inches from brands like Plano or Boyt.
How long does shipping take for an online-only firearm?
Firearm shipments require 3-5 business days for processing before they are transferred to a licensed carrier. Once shipped, transit to your chosen FFL dealer typically takes 2-7 business days depending on your location. You will need to contact your dealer directly to complete the mandatory 4473 background check upon arrival.
Can I return it if it doesn't cycle my target loads?
Returns for mechanical malfunctions are accepted within 30 days, provided the firearm is unfired and in original condition. However, most cycling issues with light target loads (under 1-1/8 oz) are resolved by switching to a more open choke or using higher-velocity ammunition—solutions we recommend trying first.
Does this work with aftermarket Carlson's choke tubes?
Yes, the HT-104 uses the common Beretta/Benelli Mobil choke threading. Aftermarket tubes from Carlson's, Briley, or Truloke in the Mobil pattern will thread in correctly. Ensure you select tubes rated for steel shot if you plan to hunt waterfowl.
