Description
There is a lot to like about a rifle that weighs four pounds, runs cheap rimfire ammo all day, and still shoots straighter than it has any right to. The KelTec SU-22CA is built on the same bones as the SU-16 series, sharing the stock and grip layout of its centerfire big brother, but it swaps the gas piston for a simple straight blowback action chambered in .22 LR. That means low recoil, easy operation, and a platform that makes sense whether you are teaching someone the fundamentals or just burning through a brick of ammo on a Saturday.
What Sets the SU-22CA Apart
This tan version pairs a Cerakote finished polymer receiver and stock with a black 16.1 inch steel barrel, and the muzzle is threaded 1/2×28 so you can add a brake or other standard muzzle attachments. Sights are handled two ways right out of the box: adjustable irons with a windage-adjustable rear and elevation-adjustable front, plus an integrated Picatinny rail on top of the receiver for a red dot or scope. Inside, a 4140 steel bolt rides on steel guide rails, which is a nice touch of durability in a polymer-framed rimfire. The fixed stock even has a built-in storage compartment, handy for stashing a spare magazine.
Feeding the KelTec SU-22
Capacity is where this rifle really shines for the money. It ships with a 26-round semi-transparent magazine, so you can see your ammo count at a glance, and it accepts most AR-22 pattern magazines, including those made for the old Atchisson M-16 conversion. Spare mags are easy to find and easy on the wallet, just like the ammo.
A Trainer That Earns Range Time
With AR-style ergonomics, a familiar magazine release location, and a crossbolt safety, the SU-22CA works well as a low-cost trainer for anyone running a modern sporting rifle. It is also just plain fun. At 34 inches overall and four pounds unloaded, it is light enough for smaller-framed folks and easy to carry for small game or pest duty. Range reports consistently note accuracy that hangs with rimfires costing quite a bit more, especially with standard velocity ammo.

Frequently Asked Questions
What magazines does the KelTec SU-22CA accept?
It ships with a 26-round semi-transparent magazine and accepts most AR-22 pattern magazines, including those built for the Atchisson M-16 conversion. That gives you plenty of affordable options for spare mags. The see-through factory mag is a nice bonus since you can check your round count at a glance.
Is the barrel on the SU-22CA threaded?
Yes, the 16.1 inch steel barrel is threaded 1/2×28 at the muzzle. That is the standard rimfire thread pitch, so it will take most common muzzle devices made for .22 LR. It comes capped and ready to shoot as-is if you prefer to leave it bare.
Can I mount an optic on the SU-22CA?
Absolutely. There is a Picatinny-style rail integrated into the top of the receiver that will take red dots, scopes, or just about any rail-mounted sighting option. The rifle also comes with adjustable iron sights, with the rear adjustable for windage and the front for elevation, so you are covered either way.
Is the KelTec SU-22CA a good first rifle for a new shooter?
It is one of the better choices out there for that job. The .22 LR chambering keeps recoil and noise to a minimum, the controls are simple and intuitive, and at just four pounds it is easy for smaller-framed folks to handle. It also mirrors the layout of KelTec's SU-16, so skills learned here carry over to centerfire rifles down the road.
