ATI Cavalry SX .410 Gauge O/U Shotgun 26″ 3″ Chamber
About this product
What is the ATI Cavalry SX .410 Gauge O/U Shotgun? The ATI Cavalry SX is a domestically-produced over-under shotgun chambered in .410 bore, designed specifically for the lightweight, low-recoil needs of upland bird hunters and sporting clays shooters moving to a smaller gauge. It features a 26-inch barrel, a 3-inch chamber for magnum loads, and includes a set of five interchangeable choke tubes to pattern loads from close-range quail to sporting clay presentations. With Turkish walnut furniture and blued steel, it bridges traditional aesthetics and modern mechanical functionality.
What is the ATI Cavalry SX .410 Gauge O/U Shotgun used for?
Its primary application is hunting upland game birds like quail, dove, and woodcock over pointing dogs, where its 6.2-pound total weight and short swing radius reduce fatigue during long walks. The .410 bore’s minimal recoil and shot payload also make it a viable training platform for new shooters or a dedicated gun for sporting clays sub-gauge competition, specifically the .410 events where shot count and precision are paramount. The five included choke tubes (Cylinder, Improved Cylinder, Modified, Improved Modified, Full) let you pattern the 1/2- to 11/16-oz shot loads effectively at ranges from 15 to 30 yards.
How does the ATI Cavalry SX .410 Gauge O/U Shotgun compare to the Stevens 555 Sporting O/U Shotgun .410 Bore 28 in?
The Cavalry SX is mechanically superior for field use but costs approximately $150 more than the Stevens 555 Sporting .410. The Cavalry SX uses auto-ejectors that positively throw spent hulls clear of the action after firing, while the Stevens uses extractors that merely lift hulls for manual removal—a meaningful difference when reloading quickly on a covey rise. The Cavalry SX's 26-inch barrel offers faster handling in thick brush, whereas the Stevens' 28-inch tube provides a marginally longer sight plane and slightly softer perceived recoil for the target line.
What does it weigh and what are the dimensions?
The shotgun weighs 6.2 pounds (98.8 ounces) and has an overall length of 42.5 inches, with a 26-inch barrel and a 14.25-inch length of pull. This makes it approximately 8 ounces lighter than many comparable 20-gauge over-unders, a significant reduction you'll feel after carrying it for three hours in the field. The barrel diameter at the muzzle is 0.725 inches for screw-in chokes, and the receiver width is 1.6 inches, contributing to its slim, fast-handling profile.
Who is this NOT for?
This is not for a hunter pursuing waterfowl, turkey, or any game requiring dense, high-energy patterns at 40+ yards, as the .410 simply lacks the necessary shot payload and energy. It's also a poor choice as a sole defensive firearm, given the limited terminal ballistics of .410 buckshot loads compared to 12 or 20 gauge. For a hunter wanting a single, versatile shotgun for everything from doves to deer, a Stevens 555 Sporting 20 Gauge would be a more pragmatic first O/U purchase.
What's in the box?
You receive the shotgun, five Beretta/Benelli Mobil-style choke tubes (C, IC, M, IM, F), a choke tube wrench, and a padded synthetic case. Notably, the manual includes a dated but legally sufficient ATF Form 4473 reference guide—something cheaper imports often omit. The oil finish on the walnut isn't protected by a hard shellac, so you'll need to apply your own paste wax or oil before first field use to guard against moisture.
Is the ATI Cavalry SX .410 Gauge O/U Shotgun worth it at $607.99?
At just over $600, it’s worth the price if you specifically want a field-grade .410 over-under with ejectors and American warranty support, as most competitors in this category are Turkish imports with extractors only. You're paying for a functional mechanical upgrade (ejectors) and domestic distributor accountability you won't get with a sub-$500 import. However, if your budget is rigid and you can live with extractors, the $459 Stevens 555 .410 provides nearly identical performance for casual use.

Pros & cons
What works
- Weighs 6.2 lbs (99 oz) — noticeably lighter than most 20-gauge O/Us for all-day carry.
- Includes 5 specific choke tubes (C, IC, M, IM, F) for patterning .410 loads from 15 to 30+ yards.
- Features auto-ejectors — a functional upgrade over extractor-only guns like the Stevens 555.
- Turkish walnut stock with 14.25-inch length of pull provides a traditional, solid cheek weld.
Trade-offs
- Oil-finished walnut requires immediate user-applied wax or oil protection — it ships unfinished for moisture resistance.
- .410 ammunition costs 60-80% more per round than 12 or 20 gauge target loads — a significant ongoing expense for practice.
- Single selective trigger lacks adjustable pull weight — it's a fixed mechanical setup, not a customizable competition unit.

Frequently asked questions
- Is it compatible with 3-inch magnum .410 shells?
- Yes, the 3-inch chamber is designed specifically for 3-inch magnum .410 shells, which typically hold 11/16 oz of shot. Always confirm your specific ammunition's length matches the chamber stamp—using 2.5-inch shells is fine, but do not attempt to chamber any shell longer than 3 inches.
- Does it fit standard Beretta/Benelli Mobil choke tubes?
- Yes, it uses the common Beretta/Benelli Mobil choke thread pattern. The included tubes are C, IC, M, IM, and F constrictions. Aftermarket tubes from brands like Carlson's or Briley in this pattern will fit, provided they are rated for .410 bore steel shot pressures.
- How long does shipping take to an FFL?
- Shipment to your selected FFL dealer typically occurs within 2-3 business days after your order and FFL information are verified. Transit time then depends on the carrier; expect 3-7 additional business days for ground service. Total time from order to FLL notification is usually 5-10 business days.
- Can I return it if there's a mechanical defect?
- Yes, American Tactical Imports (ATI) provides a one-year limited warranty on mechanical defects. If the gun fails to fire, extract, or eject due to a manufacturing flaw, contact ATI customer service for a Return Merchandise Authorization (RMA). Do not attempt repairs yourself, as this may void the warranty.
- Does this work with a limbsaver recoil pad?
- The stock has a standard curved buttplate that is not pre-drilled for a slip-on pad. To install a limbsaver, you'll need a model designed for a curved surface (like the Slip-On 10101) and may experience minor fitment issues. For a permanent solution, the stock would need to be cut and a grind-to-fit pad installed by a gunsmith.
