The ATI Cavalry SX Compact 20ga 26” O/U 3” Chamber is a youth-sized over/under that proves small shooters don’t need to compromise on quality. Built around an engraved aluminum-alloy receiver and oil-finished Turkish walnut furniture, this shotgun delivers traditional looks with a modern, reduced length of pull. The 26” barrels are 4140 chrome-moly steel, blued and chrome plated inside and out for corrosion resistance and easy cleanup. Five interchangeable MobilChokes are included, and the single selective trigger keeps operation straightforward. Per ATI specs, the overall weight lands at 6.2 lbs, making it easy for smaller frames to swing and carry all day. For an entry-level competitive or field gun under $510, the Cavalry SX Compact brings real value without the cheap feel.

Key Features
- Compact Youth Stock — The reduced length of pull lets younger or smaller-framed shooters mount the gun naturally, improving cheek weld and follow-through on clays or birds.
- 5 MobilChokes Included — You get Full, Modified, Improved Cylinder, Skeet, and Cylinder tubes right out of the box, so you can dial in pattern density for anything from trap to upland game without spending extra.
- Single Selective Trigger — One trigger controls both barrels with a simple barrel-selector switch on the tang, eliminating confusion under pressure and keeping the weight low.
- Chrome-Lined Barrels Inside and Out — The 4140 steel is fully protected against moisture and carbon fouling, which means less cleaning time and longer barrel life even with heavy use.
- Engraved Aluminum Receiver — Keeps the gun light while adding visual appeal; the engraving is subtle enough for the field but stands out at the range.
Who It’s For
This is for the tech-savvy shooter who wants an affordable, lightweight O/U for their kid, spouse, or themselves if they’re on the smaller side. If you’re into 3-gun, sporting clays, or just walking the woods for grouse and quail, the Cavalry SX Compact gives you a reliable, easy-swinging platform without the $1,000+ price tag. It’s also a smart pick for instructors who need a loaner gun that fits a wide range of new shooters.
Pros & Cons
- Pro: Sub-$510 price for a real O/U with chromed bores and walnut furniture is rare.
- Pro: MobilChoke system means you’re not locked into one pattern; tubes are easy to swap and widely available.
- Pro: Light weight (6.2 lbs) makes it a joy to carry on long hunts or during multi-stage matches.
- Con: The Turkish walnut is oil-finished and looks good, but it’s not a high-grade exhibition wood; some shooters might prefer a glossier factory stock.
- Con: The single trigger is crisp but has a bit of creep out of the box; a quick gunsmith polish can clean it up.

FAQ
What is the length of pull on the ATI Cavalry SX Compact?
The length of pull (LOP) is approximately 13.5” (per ATI specs). That’s about 1” shorter than a standard adult O/U, which helps smaller shooters mount the gun without overreaching.
Does this shotgun come with a carrying case?
No, the Cavalry SX Compact ships in a cardboard box with the five MobilChokes and a choke tube wrench. You’ll want to pick up a soft or hard case separately for transport and storage.
Is the single selective trigger adjustable?
The trigger is not user-adjustable for pull weight, but it can be tuned by a competent gunsmith if needed. Out of the box, it breaks at around 5.5-6 lbs.
Can I use steel shot through the chrome-lined barrels?
Yes, the chrome-plated bores and MobilChoke tubes are compatible with steel shot, as long as you use the appropriate choke constriction (Improved Cylinder or Cylinder recommended for steel).
