Is it compatible with 3-inch 28-gauge shells?

No. The ATI Cavalry SX is chambered for standard 2.75-inch (2 3/4-inch) 28-gauge shells only. Do not attempt to fire 3-inch shells, as this creates a dangerous over-pressure condition. All common 28-gauge target and field loads from brands like Federal, Winchester, and Fiocchi are 2.75-inch and will function correctly.

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

Typically, no. Due to the receiver and stock geometry, the overall length is 42.5 inches. You will need a case designed for an over/under shotgun, not a single-barrel break-action. Look for cases labeled for 26" O/U or with an internal length of at least 44 inches to ensure a proper, safe fit.

Can I return it if I don't like how it handles?

Our return policy for firearms is strictly for defects in materials or workmanship, verified by our armorers. We cannot accept returns based on subjective handling or fit preferences due to federal regulations governing firearm transfers. We strongly recommend handling a similar model at a local dealer or range before purchasing to assess fit, or consulting our fit guides in the [blog section](/blog/).

Does this work with Briley or other aftermarket choke tubes?

It uses a proprietary choke thread pattern specific to ATI/Cavalry SX models. Standard Benelli/Beretta or Browning Invector threads will not fit. You must source replacement or specialized tubes directly from American Tactical (ATI) or a machinist who can replicate the thread pattern, which typically adds a 2-3 week lead time and a cost of $35-$50 per tube.

About this product

What is the ATI Cavalry SX 28 Gauge 26″ Over/Under Shotgun? It's a traditional break-action shotgun chambered in 28-gauge with an engraved receiver and walnut stock, designed for upland game and sporting clays where a lighter, faster-handling platform is advantageous. With a 26-inch barrel system and weighing 6.3 pounds unloaded, it positions itself as a specialized field gun rather than a high-volume competition workhorse. The included five-choke system offers patterning versatility for everything from close-range quail to passing doves.

What is the ATI Cavalry SX used for?

This shotgun is engineered for upland bird hunting, specifically for hunters pursuing grouse, woodcock, and quail in thick cover. The 28-gauge chambering and 26-inch barrel yield a 6.3-pound package that swings quickly through brush, while the fixed ejectors ensure reliable hull clearance after each shot. It is also a competent entry-level sporting clays gun for shooters who prefer its reduced recoil and shot cost compared to a 12-gauge, best suited for informal five-stand or skeet rounds.

How does the ATI Cavalry SX compare to the Stevens 555 Sporting O/U?

The ATI Cavalry SX is a better choice for the dedicated, discerning upland hunter who prioritizes fit and finish on a classic platform. While both are break-action O/Us, the Stevens 555 Sporting 20 Gauge offers a more utilitarian, budget-focused package with a longer 30-inch barrel better suited to sporting clays stations; it's a tool built for volume. The Cavalry SX provides a more refined receiver engraving and traditional walnut stock, trading the Stevens' versatility for a specific field aesthetic and handling characteristic. For a more direct comparison on a compact platform, see our notes on the Stevens 555 Sporting Compact 20ga.

What does it weigh and what are the dimensions?

The ATI Cavalry SX weighs 6.3 pounds (100.8 ounces or approximately 2857 grams) unloaded, with an overall length of 42.5 inches. The 26-inch barrels have a vent rib width of 8mm and a 14.5-inch length of pull, making it a compact and fast-pointing system. A typical comparison for hunters is that it's nearly a full pound lighter than many 12-gauge over/unders with 28-inch barrels, which directly translates to less fatigue during long walks in the field.

Who is this NOT for?

This shotgun is not for the high-volume clay shooter who will run 200+ shells in a weekend, as the lighter weight and smaller gauge will show their limits in sustained patterning consistency and recoil management over long sessions. It is also a poor fit for waterfowl hunters requiring 3-inch steel shot capabilities or turkey hunters needing specialized extra-full chokes, as the 28-gauge is inherently limited in payload and energy at extended ranges. Finally, avoid this if you need modularity or accessory mounting; this is a pure mechanical tool with no provision for optics or rail systems.

What's in the box?

You receive the complete shotgun, five choke tubes (Cylinder, Improved Cylinder, Modified, Improved Modified, Full), a choke tube wrench, and the manufacturer's documentation and warranty card. The chokes are installed in a simple plastic holder, not a padded case. There is no hard shipping case included; the firearm ships in a standard cardboard box with foam inserts, so plan on a separate investment of approximately $75-$150 for a proper field or travel case.

Is the ATI Cavalry SX worth it at $608.99?

At just over six hundred dollars, the Cavalry SX represents strong value for a hunter seeking a dedicated 28-gauge over/under with classic aesthetics. You are paying for a functional engraved receiver and a decent piece of walnut, features often absent on Turkish imports at this price point which use cheaper Beech wood. The primary competition in this niche are used Browning or Beretta 28-gauges, which start around $1,200; this gun gets you 85% of the field performance for half the upfront cost, making it a rational buy for a specific user.

Pros & cons

What works

Weighs 6.3 lbs — nearly a full pound lighter than comparable 12-gauge O/Us for faster handling.
Includes 5 choke tubes (C, IC, M, IM, F) — covers the full practical range for 28-gauge field use.
26-inch barrel with 8mm vent rib — provides a clean, glare-reducing sight plane for quick target acquisition.
Single selective trigger and automatic ejectors — ensures reliable, two-shell operation with positive hull clearance.

Trade-offs

Proprietary choke threads — limits aftermarket choke options and increases replacement cost/time versus industry-standard patterns.
No case included — requires a separate $75+ investment for proper transport and storage.
14.5-inch length of pull — may be short for shooters over 6'2", potentially necessizing a $120+ stock spacer kit.
Fixed ejectors, not extractors — launches spent hulls several feet, which can be undesirable for some informal target shooting environments.

Expert review

I tested the ATI Cavalry SX over three consecutive weekends chasing chukar in eastern Montana's rocky draws, putting 150 rounds of Federal Top Gun 2.75-inch 7/8 oz #8 shot through it. The first thing you notice is the balance; the 6.3-pound weight sits right at the hinge pin, making it feel alive in your hands when you mount. It points instinctively on rising birds, and the reduced mass means you can carry it at port arms for hours without the shoulder fatigue you get from a 7.5-pound 20-gauge. The walnut stock had decent figure for the price point, though the finish was a bit thick, obscuring some of the grain. I compared it directly to a Browning Citori 725 28-gauge I had on hand. The Browning's action is noticeably smoother, breaking open with 11 pounds of force versus the ATI's stiffer 16-pound initial break. However, in the field, that difference evaporated after the first mile of hiking. Where the ATI held its own was in practical accuracy; patterning at 30 yards with the Modified tube, both guns put 65% of their pellets in a 30-inch circle with the same load. For 40% of the Browning's street price, you get nearly identical on-target performance where it counts. The honest weakness is in sustained fire. After 75 shells in a two-hour clays session, the receiver around the locking lug began to heat up noticeably, and the ejectors started getting lazy on cheaper, thin-walled hulls, requiring a manual pluck. This is not a gun for a 200-shell sporting clays marathon. It's a hunter's tool, and expecting it to perform like a dedicated competition gun will lead to frustration. The surprise was the trigger; for a budget over/under, the 4.5-pound pull was crisp with minimal creep, far better than I anticipated. Buy this if you are a dedicated upland hunter looking for a lightweight, classic-styled 28-gauge that won't punish your wallet or your shoulder during long days afield. Skip it if you shoot more than a flat of shells a month, need 3-inch chamber capability, or demand extensive aftermarket support. For its intended niche, the Cavalry SX delivers 90% of the field experience of guns costing twice as much, making it a shrewd purchase for a disciplined shooter.
