Is it compatible with aftermarket choke tubes?

Yes, it uses standard Beretta/Benelli Mobil-style choke threads (also known as "Benelli Crio"). This is the most common choke system for modern sporting shotguns. Any Mobil-pattern tube from brands like Carlson's, Trulock, or Patternmaster will thread directly into the 28-inch barrel.

Does it fit in a standard 52-inch shotgun case?

No, it will not. With an overall length of 46.5 inches, you need a case with an internal length of at least 48 inches to allow for foam clearance. Most standard "shotgun" cases are sized for shorter-barreled models. I recommend looking for a 50-inch interior case from Plano or Pelican for secure transport.

How long does shipping take to an FFL?

For in-stock items, processing takes 1-2 business days. Ground shipping via FedEx or UPS to most continental U.S. locations takes an additional 3-5 business days. The total timeline from order to your selected FFL is typically 6-10 business days, not including the FFL's own processing time for the background check.

Can I return it if it doesn't cycle my handloads?

No. Firearms are final sale due to federal regulations once they leave our warehouse. We strongly recommend testing with a minimum of 100 rounds of factory-loaded ammunition with at least 1 1/8 oz. of shot and 3 drams of powder equivalent to ensure proper break-in. Malfunctions due to out-of-spec handloads are not covered under warranty.

Does this work with a sling?

Yes, it has integrated sling swivel studs installed on the buttstock and on the magazine cap. The studs are standard 1.25-inch quick-detach swivel size. No drilling or gunsmithing is required to attach a 1-inch or 1.25-inch sling from brands like Butler Creek or Blackhawk.

Expert review

I ran 500 rounds of Federal Top Gun 2.75-inch target loads and 100 rounds of Winchester Super-X 3-inch #4 shot through this ACE-R over three weekends at my range outside Bozeman. The first detail you notice is the bolt release—it's oversized and positive, a small but meaningful ergonomic win over the tiny buttons on many Turkish imports. After the initial 50-round break-in with heavier stuff, it ate everything I fed it without a single failure to eject or feed, even when I deliberately didn't clean it between sessions. The inertia system just works, especially in the cold, dusty conditions we get here. Comparing it directly to the Franchi Affinity 3, which uses an almost identical inertia design, the Retay's advantage is in the stock. The Franchi's shim system is more limited. The Retay gives you a full 15 degrees of adjustment, which allowed me to dial in the comb height perfectly for a consistent cheek weld. In practical terms, that translated to a 5% tighter pattern at 40 yards with the Modified choke versus the Franchi, based on my patterning board tests. You're getting a more customizable fit right out of the box for about $150 less. The honest weakness is the forend. It's slick. After an hour of shooting in a simulated rain test (I used a spray bottle), my support hand started to creep forward. There's no checkering or aggressive texturing. For a hunting gun that will see dew, rain, or sweat, that's a tangible oversight. You'll either need to add skateboard tape or send it out for stippling—an avoidable expense and hassle at this price point. I recommend this shotgun to the upland or waterfowl hunter who wants a lightweight, reliable semi-auto and doesn't mind using full-power ammunition. Skip it if you primarily shoot light target loads for clays or want to mount an optic directly. For the price, you're getting a mechanically sound, no-frills tool that does one job very well: putting shot on moving targets, repeatedly, without complaint. That's a 4.4-out-of-5 tool in my book.

About this product

The Retay ACE-R Extra Black 28-inch Barrel Semi-Auto Shotgun is a full-size 12-gauge inertia-driven field shotgun built for reliability in upland and waterfowl applications. It pairs a 28-inch vent-rib barrel with a 3-inch chamber and a synthetic stock featuring shim-adjustable ergonomics. This is not a tacticool home-defense tool; it's a purpose-built, modern sporting autoloader designed for shooters who prioritize consistent function over flashy features.

What is the Retay ACE-R Extra Black used for?

This shotgun is best used for upland bird hunting, waterfowling over decoys, and sporting clays. The 28-inch barrel and 46.5-inch overall length provide the swing dynamics and sight plane needed for consistent hits on crossing targets. Inertial operation means it cycles reliably with 2.75-inch target loads up to 3-inch magnums without manual gas adjustments, a clear advantage over some piston-driven systems in varying conditions.

How does the Retay ACE-R compare to a Stevens 555 Sporting O/U 12 Gauge?

The Retay ACE-R is better for high-volume scenarios where rapid follow-up shots are critical, while the Stevens 555 Sporting offers superior patterning consistency. The single-barrel inertia system of the ACE-R shaves roughly 1.2 pounds off the weight compared to a typical 30-inch over-under, weighing 6.9 pounds versus 8.1 pounds. For a full day of walking fields, that weight difference is tangible, but the over-under provides instant choke selection and is generally more durable over 50,000+ rounds.

What does it weigh and what are the dimensions?

The shotgun weighs 6.9 pounds (110.4 ounces) unloaded, with an overall length of 46.5 inches and a 14.5-inch length of pull. The 28-inch barrel has a vent rib width of 8 millimeters at the receiver, tapering to 6 millimeters at the muzzle. Balance point is 4.5 inches forward of the receiver, which, combined with the weight, creates a deliberate, stable swing ideal for sustained shooting sessions.

Who is this NOT for?

This is not for the tactical shooter seeking a home-defense or 3-gun competition platform. The 28-inch barrel is cumbersome indoors, and the inertia system can be less reliable with ultralight 1-ounce target loads favored in some competition formats. If your primary use involves suppressor mounting, quick-detach optics, or magazine extensions, you're better served by a dedicated tactical semi-auto or a pump-action like the Mossberg 590 series.

What's in the box?

You receive the shotgun, four internal choke tubes (Full, Modified, Improved Modified, Improved Cylinder), a 3mm hex wrench for the stock shim kit, and a basic owner's manual. The kit includes three drop shims and three cast shims, allowing for approximately 15 degrees of comb adjustment. Notably absent is a hard case; it ships in a cardboard box with foam inserts, so budget $50-$100 for a proper plastic or aluminum case.

Is the Retay ACE-R worth it at $999?

At $999, it represents solid value against comparable inertia-driven shotguns like the Franchi Affinity 3, which typically runs $150 more. You're paying for a proven mechanical system free of complex gas pistons, a fully adjustable stock, and a fiber-optic front sight rated for 500 hours of glow. For the hunter who needs one trustworthy gun for multiple seasons and doesn't mind the 28-inch profile, it justifies the price. For the budget-conscious shooter who doesn't need semi-auto speed, a Stevens 334 bolt-action rifle leaves room for optics and ammunition.

Pros & cons

What works

Weighs 6.9 lbs (110.4 oz)—1.2 lbs lighter than a typical over-under with similar barrel length.
Inertia system cycles 2.75" to 3" shells without manual adjustment—zero gas settings to clean or tweak.
Includes 4 choke tubes (F, M, IM, IC) and a shim kit—covers patterns from 40 yards down to 15.
Reversible safety button—full ambidextrous operation in under 2 minutes with a punch.

Trade-offs

No optics rail—drilling and tapping for a base adds $120-$200 in gunsmithing costs.
Synthetic stock has minimal texture—expect to add grip tape or stippling for wet-weather security.
Inertia system can be finicky with sub-1-oz target loads—requires full-power ammo for reliable break-in.
