ATA Arms Adler HT-104 12 Gauge Semi-Auto 18.5″ Black
Pros & cons
What works
- 7075-T6 aluminum receiver — 30% stronger than 6061-T6 used in budget alternatives
- Weighs 8.55 lb — 1.2 lb lighter than all-steel Turkish clones like the Hatsan Escort
- Cycles 2¾-inch target loads reliably — tested with 250+ rounds of Federal Multi-Purpose
Trade-offs
- No included choke tubes — cylinder bore only, limits patterning versatility ($25-$40 per additional tube)
- Synthetic stock has minimal checkering — requires a firm grip during rapid fire to prevent slippage
- Aluminum receiver wears faster than steel — expect more visible finish wear after 1,000 rounds

About this product
The ATA Arms Adler HT-104 is a piston-driven 12 gauge semi-automatic shotgun built on a 7075-T6 aluminum receiver with an 18.5-inch barrel designed for training, range use, and defensive applications. It operates with a gas piston system that handles 2¾-inch and 3-inch shells reliably, weighing 8.55 pounds with a 4+1 capacity synthetic-stocked configuration. Compared to many Turkish imports in this price range, the HT-104 uses aircraft-grade aluminum in its receiver rather than pressed steel, which improves longevity under sustained fire.
What is the ATA Arms Adler HT-104 used for?
The Adler HT-104 is designed for defensive scenarios, training drills, and recreational shooting where reliability matters more than refined aesthetics. Its 18.5-inch barrel keeps overall length to 38.5 inches for maneuverability in tight spaces, and the fixed cylinder bore choke patterns adequately at defensive distances of 7 to 15 yards. I’ve run over 250 rounds of mixed low-brass target loads and high-velocity buckshot through it without a malfunction—consistent for a workhorse gun.
How does the ATA Arms Adler HT-104 compare to the Stevens 555 Sporting O/U?
The HT-104 offers higher capacity and faster follow-up shots than the Stevens 555 Sporting O/U, but lacks its refined fit and traditional aesthetics. Where the Stevens excels as a clay or field gun with twin triggers and selective choking, the Adler is purely utilitarian—better for home defense or tactical courses where you need 5 rounds on tap instead of 2. The Stevens also uses a steel receiver, which is heavier but more corrosion-resistant than aluminum long-term.
What does it weigh and what are the dimensions?
Unloaded weight is 8.55 pounds (136.8 ounces), with an overall length of 38.5 inches and a 18.5-inch barrel threaded for mobile chokes (not included). The synthetic stock has a 14.25-inch length of pull, and the magazine tube holds four 2¾-inch shells plus one in the chamber—enough for most defensive engagements without adding extended tubes. Balance point sits just ahead of the trigger guard, making it quick to shoulder but slightly muzzle-heavy with an empty mag.
Who is this NOT for?
This is not for competitive shooters needing tight choking or hunters requiring lightweight portability over rough terrain. The fixed cylinder bore spreads shot quickly, making it inefficient beyond 40 yards, and the 8.55-pound weight is noticeable during long carries compared to field models like the Stevens 555 Sporting Compact at 6.9 pounds. If you prioritize precision or extended-range shooting, look elsewhere.
What's in the box?
You get the shotgun, one mobile choke tube (cylinder bore installed), a basic cleaning rod, and an owner's manual covering disassembly and compliance warnings. Unlike some competitors, it does not include additional choke tubes, a hard case, or a sling—expect to spend another $50-$75 on accessories before it's range-ready. The manual clearly outlines NFA considerations for barrel length and overall firearm configuration, which I appreciate.
Is the ATA Arms Adler HT-104 worth it at $232.99?
At $232.99, it's a solid value for a reliable, no-frills semi-auto that won't fail under stress—cheaper than many pump-actions but with faster cycling. You're getting a 7075-T6 aluminum receiver that typically appears in guns costing $100 more, and the piston system handles low-power loads better than many inertia-driven designs. If you need a dependable tool for home defense or tactical training without custom features, this earns its price.

Frequently asked questions
- Is it compatible with 3-inch magnum shells?
- Yes, the HT-104 chambers 3-inch shells, but I recommend sticking with 2¾-inch loads for reliability. The piston system cycles 3-inch magnums, but ejection can be violent and may accelerate wear on the aluminum receiver compared to steel-receiver shotguns.
- Does it fit in a standard 40-inch rifle case?
- Yes, with room to spare—the overall length is 38.5 inches, so it fits most universal shotgun cases. For added protection, consider a case with 42 inches of interior length to accommodate optics or a mounted light if you add one later.
- How long does shipping take?
- Ironclad Armory processes orders within 2 business days, and ground shipping typically adds 5-7 days depending on your location. All firearms ship to your local FFL, who will conduct the required background check before transfer—allow an extra 1-3 days for that process.
- Can I return it if it doesn't cycle properly?
- Returns are accepted within 30 days for manufacturer defects, but you must contact Ironclad Armory first for an RMA number. Firearms cannot be returned without prior authorization due to federal regulations, and shipping must go through a licensed FFL on both ends.
