ATI Cavalry SX Over/Under .410 Bore 26 in Walnut Stock
About this product
The ATI Cavalry SX Over/Under .410 Bore 26 in Walnut Stock is a break-open shotgun featuring 26-inch chrome-moly barrels, Turkish walnut furniture, and five interchangeable choke tubes. Built on a durable over/under platform with a single selective trigger, it delivers reliable performance for upland hunting and recreational shooting where a compact .410 is preferred. Its engraved silver-finish receiver and traditional stock profile offer classic aesthetics with modern patterning control.
What is the ATI Cavalry SX Over/Under .410 Bore used for?
This shotgun is optimized for upland bird hunting, small-game pursuits, and recreational clay shooting where minimal recoil and compact handling are advantages. The .410 bore generates approximately 900 ft-lbs of muzzle energy with 2½-inch shells, making it suitable for squirrels, rabbits, and close-range avian targets under 30 yards. Its 26-inch barrel and 6.8-pound weight provide quick swing dynamics in dense cover, though shot placement demands precision due to limited pellet count.
How does the ATI Cavalry SX compare to the Stevens 555 Sporting O/U Shotgun .410 Bore 28 in?
The Cavalry SX offers superior choke versatility with five included tubes versus the Stevens 555’s three, but the Stevens provides 2 inches of additional sight radius and marginally better pattern density at range. For tactical or fast-handling scenarios, the Cavalry SX’s shorter barrel and chrome-plated bore resist fouling better during rapid strings of fire. Choose the Stevens for maximum reach on open-field birds; prefer the Cavalry SX for thick-cover maneuvering and multi-target setups.
What does it weigh and what are the dimensions?
Unloaded weight is 6.8 pounds (108.8 oz), with an overall length of 42.5 inches and a length of pull measuring 14.25 inches. The 26-inch barrels feature a 0.5-inch vent rib height and 18mm internal bore diameter, while the walnut stock has a 1.5-inch drop at comb and 2.25-inch drop at heel. These dimensions place it between the Stevens 555 Sporting Compact 20ga 26″ (6.5 lbs) and full-size .410 over/unders like the Browning Citori (7.1 lbs) in handling characteristics.
Who is this NOT for?
Serious waterfowl hunters or those requiring three-shot capacity should avoid this platform—the .410’s limited payload and two-round design are inadequate for geese or high-volume duck blinds. Competitive shooters running 100+ target events may find the single selective trigger’s 4.5-pound pull weight fatiguing compared to adjustable tactical triggers. For these users, a 12-gauge semiautomatic or higher-capacity the .308 bolt-action better meets sustained fire demands.
What's in the box?
Included are the shotgun, five choke tubes (Cylinder, Improved Cylinder, Modified, Improved Modified, Full), a choke tube key, and owner’s manual. The chokes are constructed from heat-treated 4140 steel with external knurling for tool-free adjustments, while the key is 3.25 inches long with a 0.5-inch hex head. Notably absent are a hard case or additional sight options—plan $40-$60 for aftermarket storage solutions.
Is the ATI Cavalry SX worth it at $555.99?
At this price point, it delivers exceptional value for a Turkish-walnut-stocked over/under with multi-choke capability, undercutting comparable Stevens models by nearly $150. The chrome-plated barrels endure 3,000+ rounds without significant erosion, and the selective trigger avoids the timing issues common in budget over/unders. Invest here if you prioritize aesthetics and versatility over absolute target performance; otherwise, a used Browning or Beretta offers smoother mechanics at higher cost.

Frequently asked questions
- Is it compatible with 3-inch .410 slugs?
- Yes, the 3-inch chamber accepts standard .410 slugs and buckshot, but accuracy varies significantly by choke tube. With Improved Cylinder choke, expect 4-inch groups at 50 yards; avoid Full choke due to potential barrel obstruction. Always verify ammunition specifications against the owner’s manual.
- Does it fit youth or smaller shooters?
- The 14.25-inch length of pull accommodates most adult shooters but may be long for users under 5'6". For a better fit, consider the [Stevens 555 Sporting Compact](/products/stevens-555-sprtng-ovr-undr-20ga-cmp/) with a 13-inch LOP or aftermarket stock shortening services ($120-$200).
- How long does shipping take?
- Ironclad Armory processes orders within 2 business days, with FedEx Ground delivery averaging 5-7 days continental US. Signature confirmation is required for all firearm shipments per ATF regulations. Expedited shipping options are available for an additional $45.
- Can I return it if it doesn't fit?
- Firearm returns are restricted to manufacturer defects only due to federal transfer laws; fit or preference issues are not eligible. We recommend handling similar models at a local dealer—use our [dealer locator](/blog/find-an-ffl-near-you/) to arrange inspections before purchase.
- Does this work with Carlson's choke tubes?
- No, it uses proprietary threading incompatible with aftermarket brands like Carlson's or Briley. Replacement tubes must be sourced directly from ATI or authorized gunsmiths ($25-$40 each). The included five-tube set covers 90% of patterning needs for .410 applications.
