Kel-Tec SU22 Review: The Compact 26+1 .22 Carbine

The SU22 is a rimfire built around being small, light and high-capacity. That makes it a fun range gun and an awkward one to compare with the usual 10/22.

Short answer

The Kel-Tec SU22 is a compact semi-auto .22 LR carbine with 26+1 magazine capacity per the listings. It suits shooters who value size, capacity and a modern layout over the vast parts support of a 10/22. Feed it high-velocity plated ammunition and test its magazines.

A different idea of what a .22 rifle is

Most .22 rifles you see at a range are variations on a familiar wooden or synthetic sporter. The Kel-Tec SU22 comes from a different school: a compact, modern-looking semi-auto designed around a big magazine and a small footprint. If you are comparing it against a Ruger 10/22, you are comparing two answers to different questions.

The listings give us enough to frame the question. The SU22 in black and the second SU22 variant both show a 26+1 capacity. The second listing is a different variant, and its web address mentions a 10 alongside the 26+1, which may point to a reduced-capacity configuration. Compare the details before you order, especially magazine capacity and any state-compliance notes.

This review is built from the listings, Kel-Tec's published layout and general rimfire reasoning. We have not fired this rifle. Specifications not shown on the listing, such as weight and dimensions, should be taken from Kel-Tec's spec sheet.

What makes it different

Capacity. Twenty-six rounds in a magazine is a big step above the ten-round rotary magazine most 10/22s ship with. That changes the character of range time: fewer reloads, more shooting. Many shooters like that; others find extended capacity unnecessary for a .22 and prefer simpler magazines.

Compact layout. The SU22 follows Kel-Tec's compact-carbine design language. The SU22 is generally described as a compact carbine with a folding stock, so it packs small for storage and travel. Confirm the exact stock configuration and how the fold works on the model you are buying; that is a spec to read, not to assume.

Modern handling. It has the controls and silhouette of a tactical rimfire, which is why it appears in our tactical .22 roundup alongside the GSG-16 and the M&P15-22.

The 10/22 comparison, honestly

The Ruger 10/22 wins on a few fronts that matter:

Parts, upgrades and stocks are everywhere.
Gunsmiths know it intimately.
Magazines are simple, inexpensive and widely available.

The SU22 wins on others:

Capacity per magazine.
A compact format for storage and travel.
A distinctive look and handling that some shooters prefer.

Question	SU22	Ruger 10/22
Magazine capacity (listing)	26 rounds	10 rounds (rotary)
Aftermarket support	Smaller	Enormous
Compactness	A selling point	Takedown versions pack small
Ease of customizing	Modest	Almost unlimited
Best for	Capacity and compact format	Versatility and upgrades

If your goal is a rifle you will modify over a decade, buy the 10/22. If your goal is a compact, high-capacity plinker and you want the novelty of something different, the SU22 is a legitimate choice.

Ammunition and magazines

As with every blowback semi-auto, the first recommendation is high-velocity copper-plated ammunition. The bullet nose shape matters too: round-nose solids generally feed more smoothly than blunt hollow points in marginal actions. Our guide to the Aguila Super Extra family is a starting point on the plated bulk side.

The magazine is the other variable. A 26-round rimfire magazine has a lot of rounds stacked in one body, which means more places for rims to overlap and more reliance on the follower spring. Treat it as a component:

Number your magazines.
Load carefully, and don't skip the seating habits recommended in the manual.
If stoppages follow one magazine, retire it.

The magazines and loaders roundup covers tools that help, and the jam troubleshooting guide explains the diagnosis.

As a suppressor host

The SU22 is often mentioned as a rimfire suppressor host. Two facts to check, not assume:

Is your variant threaded? The listings do not state it in their headline. Read the specification block on the exact model.
What are the rules where you live? Suppressors are regulated federally and by states, and the situation has been changing. SuppressorReady's rimfire hosts article covers hosts in detail.

Suppressed rimfire shooting fouls the action faster than unsuppressed. Subsonic ammunition may not cycle a blowback rifle reliably, so test before relying on it. See suppressor fouling and the subsonic comparison.

Cleaning and maintenance

Compact rimfire carbines have tight spaces, and a rifle that fouls quickly is a rifle that benefits from regular cleaning. The chamber, bolt face and extractor are the first places to look when reliability drops. Kel-Tec's manual describes takedown, and you should follow it exactly rather than improvising.

Rimfire ammunition leaves wax and lead in the action, and suppressed shooting adds to the load. Plan on a bore rod, a chamber brush and a small set of picks. Our cleaning kit roundup covers what to buy, and keeping a log of what you shot and when you cleaned makes stoppage patterns easier to spot.

Sights and optics

A compact carbine often means a compact sight setup. Check what sights come with the model you choose and what rail space is available for an optic. A small red dot suits the short, handy format; a scope adds bulk and defeats some of the point of a compact rifle. Our rimfire optics roundup walks through the options.

Who should buy it

Buy the SU22 if:

You want a compact, high-capacity .22 that stores small.
You like the idea of a modern-looking rimfire that is not another 10/22.
You are comfortable testing ammunition and magazines.

Skip it if:

You want a platform with a huge upgrade ecosystem.
You want the most predictable out-of-the-box reliability.
You need a precision rifle; look at a bolt-action instead, and see our bolt vs semi-auto guide.

A buying checklist

Confirm the exact variant, barrel configuration and magazine capacity.
Check Kel-Tec's spec sheet for weight, dimensions and stock details.
Make sure your state's rules permit the configuration.
Plan on a handful of spare magazines and a break-in with high-velocity plated ammunition.
Read the warranty terms before you need them.

Frequently asked questions

How many rounds does the Kel-Tec SU22 hold?

The listings show 26+1, meaning a 26-round magazine plus one in the chamber. One listing's web address also mentions a 10, which may indicate a reduced-capacity configuration, so check the exact model against your state's rules.

Is the SU22 good for suppressed shooting?

It is often discussed as a rimfire suppressor host, but confirm whether the specific variant you are buying is threaded. Suppressor ownership is federally and state regulated, so verify current requirements.

What ammo should I use in an SU22?

High-velocity copper-plated ammunition is the usual starting point for blowback semi-autos. Test a few magazines and avoid judging it on standard-velocity target loads.

Is the SU22 better than a Ruger 10/22?

They solve different problems. The SU22 emphasizes compactness and capacity; the 10/22 has an enormous aftermarket and an easier path to customization. Neither is universally better.
