About this product
What is the RETAY USA ACE-R Extra Black 12ga 28″ 3.5″ Semi-Auto? The RETAY ACE-R Extra Black is a full-size 12-gauge semi-automatic shotgun built for high-volume waterfowl and turkey hunting with its capability to handle 3.5-inch magnum shells. It uses a field-proven inertia piston system for reliability in adverse conditions, differentiating it from standard gas-operated competitors. The combination of a 28-inch vent-rib barrel and a lightweight synthetic stock offers a balanced platform for sustained carrying and quick target acquisition over varied terrain, a core requirement for serious migratory game hunters.
What is the RETAY USA ACE-R Extra Black 12ga 28″ 3.5″ Semi-Auto used for?
The ACE-R Extra Black is built for waterfowl and turkey hunting where 3.5-inch magnum shells are standard. Its 28-inch barrel provides the extended sight plane ideal for passing game, while the inertia piston system ensures reliable function with heavy fouling from waterfowl loads in wet, dirty conditions. The included suite of five MaraPro chokes lets you pattern effectively from 25-yard turkey shots to 45-yard duck passes, making it a true multi-species magnum tool.
How does the RETAY USA ACE-R Extra Black 12ga 28″ 3.5″ Semi-Auto compare to the Stevens 555 Sporting O/U 12 Gauge?
The ACE-R offers faster follow-up shot potential and higher shell capacity than the break-action Stevens 555 Sporting, but with less inherent precision. The ACE-R is a 3+1 inertia-driven semi-auto weighing 6.94 lbs, better suited for waterfowl blinds where rapid multiple shots at flocks are common. The Stevens 555 is an over-under with 3-inch chambers and dual barrels for clays and upland game, offering quicker barrel cooling and point-of-impact consistency but limiting you to two rounds. For chasing geese and ducks with magnum loads, the ACE-R’s semi-automatic function and 3.5-inch chamber are clear advantages; for controlled-range sporting clays or a walk-up pheasant gun, the Stevens 555 O/U provides a more traditional and fundamentally precise platform.
What does it weigh and what are the dimensions?
The shotgun balances at 6.94 lbs (3.15 kg) unloaded, with an overall length of approximately 49.5 inches. The standard 28-inch barrel with a vent rib measures a consistent 0.725 inches at the muzzle for choke threading. The synthetic stock features a 14.5-inch length of pull measured from the trigger face to the center of the Airy Pad, which itself is a primary component of the recoil management system and measures approximately 5 inches tall by 1.75 inches wide at its contact point.
Who is this NOT for?
This is not the shotgun for a new shooter seeking a soft-recoiling intro to the sport or for a home defense role where maneuverability is paramount. The 3.5-inch magnum chamber and 6.94lb weight, while assets in the field, generate substantial recoil even with the Airy Pad and make the 49.5-inch-long gun cumbersome in tight hallways or vehicles. If your primary application is 2.75-inch target loads for clays or you require a simple, single-shell tool for driven game, a dedicated trap model or a break-action shotgun like the Stevens 555 will serve you better with less felt kick and mechanical complexity.
What's in the box?
You receive a complete field-ready kit including the shotgun with a fiber optic bead front sight installed, a zippered hard case, and a modular choke set. Specifically: one C, one IC, one M, one IM, and one F MaraPro choke tube; a choke tube wrench; five shims for drop and cast adjustment; and a user manual detailing RETAY-specific takedown procedures. The accessory count totals twelve separate pieces not including the manual or case, a comprehensive package that exceeds most competitors' bare-bones offerings.
Is the RETAY USA ACE-R Extra Black 12ga 28″ 3.5″ Semi-Auto worth it at $999?
At $999, this shotgun delivers exceptional value against Italian-made inertia guns but demands you prioritize magnum-shell functionality over all else. You are paying for the 3.5-inch chamber capability, the Airy Pad system engineered to mitigate the 20-30% increase in free recoil energy of such shells, and a five-choke array that would cost $150+ separately. If your season is predicated on 3-inch shells or under, a $700-800 gas-operated semi-auto may offer softer perceived recoil. Conversely, if you need to reach out to 60+ yards for late-season Canada geese with tungsten super shot, the ACE-R’s reliability and recoil management at this price point are nearly impossible to match, making it a targeted investment for serious waterfowl hunters.

Pros & cons
What works
- Chambered for 3.5-inch magnum shells – handles the heaviest waterfowl and turkey loads on the market.
- Weighs 6.94 lbs – balances the 28-inch barrel well for sustained carrying without front-heavy fatigue.
- Includes five MaraPro chokes (C, IC, M, IM, F) – a $150+ value covering every field patterning need from cylinder to full.
- Airy Pad recoil system directly addresses the 20-30% higher felt recoil of 3.5-inch magnums versus 3-inch loads.
Trade-offs
- Proprietary MaraPro choke system – incompatible with the common Beretta/Benelli Mobilchoke thread pattern, locking you into RETAY-specific tubes.
- Fixed 3+1 magazine capacity – non-removable tube prevents aftermarket extensions for higher round counts in competitive settings.
- Inertia system requires proper mounting technique – limp-wristing or incorrect stock placement can induce short-stroking with lighter 2.75-inch target loads.

Frequently asked questions
- Does it work with 2.75-inch target loads?
- Yes, the inertia system is designed to cycle standard 2.75-inch field and target loads down to 1 1/8 oz reliably, but you must ensure the correct choke is installed for safety and optimal patterning, and performance is most consistent with shells generating at least 3 drams equivalent of powder.
- Is it compatible with aftermarket choke tubes?
- The ACE-R uses RETAY's proprietary MaraPro thread pattern (not standard Beretta/Benelli Mobilchoke), severely limiting third-party options. Your choke selection is effectively confined to RETAY's factory offerings or custom orders from a select few manufacturers like Carlson's, which typically require a 4-6 week lead time for threading.
- Can I install a magazine tube extension?
- No, the magazine tube is non-removable and integrated into the receiver as a single forging; the 3+1 capacity is fixed. This design choice prioritizes receiver strength and inertia system alignment over modularity, a trade-off hunters should understand before purchase.
- How long does shipping take to an FFL?
- Ironclad Armory processes in-stock firearms for shipping within 1-2 business days, with transit times averaging 3-5 business days for ground service to your selected FFL dealer, who must then conduct the mandatory 4473 background check before transfer.
- Does it include a hard case?
- Yes, it ships in a fitted, zippered hard case with pre-cut foam, providing adequate protection for transport to and from the range or field, though the latch system is basic and not recommended for checked airline baggage without additional padding.
