Description
There are plenty of .22 rifles out there, but the KelTec SU22CA does its own thing. It borrows its layout from the SU16 family, yet it is a dedicated .22 LR from the ground up rather than a conversion kit bolted onto something else. That means a proper blowback action with a 4140 steel bolt riding on steel guide rails inside the lightweight polymer receiver, with the recoil spring tucked above the barrel. The result is a full-size rifle that weighs right around 4 pounds, which is easy to hand to a new shooter or stash behind the seat of the truck.
Ready for Optics or Irons Out of the Box
The SU22CA ships with usable sights from day one. The rear is adjustable for windage and the front handles elevation, so you can dial in your zero without buying anything extra. When you are ready to upgrade, the integrated Picatinny rail on top takes red dots, scopes, whatever you like, and the compact forend adds a rail section for a light or bipod. The 16.1 inch barrel is threaded 1/2×28 at the muzzle, so standard rimfire muzzle devices spin right on.
26 Rounds of Cheap, Quiet Fun
Capacity is where this rifle earns its keep at the range. The included semi-transparent 26-round magazine keeps you shooting longer between reloads, and the SU22 platform accepts most AR-22 pattern mags, so spares are easy to come by. The buttstock even has a built-in storage compartment, a handy carryover from the SU16 line for stashing a spare mag or small gear.
Why the SU22CA Earns a Spot in the Safe
Between the soft-shooting .22 LR chambering, mild report, and simple crossbolt safety, this is a great trainer for beginners and a fun plinker for everyone else. The OD green furniture gives it some character, and it pulls double duty on squirrels and small game when the season rolls around. If you want a lightweight, high-capacity rimfire that does not take itself too seriously, this one delivers.

Frequently Asked Questions
Does the KelTec SU22CA take AR-22 magazines?
Yes. Beyond the included 26-round semi-transparent factory mag, the SU22 platform accepts most AR-22 pattern magazines, including those built for the Atchisson M16 conversion. That gives you a wide selection of affordable spares in various capacities.
What is the thread pitch on the SU22CA barrel?
The muzzle is threaded 1/2×28, which is the standard pitch for rimfire and .22 caliber muzzle devices. Standard attachments like muzzle brakes and other threaded accessories will fit without adapters.
Can I mount a red dot or scope on the SU22CA?
Absolutely. The polymer receiver has an integrated Picatinny rail up top that accepts red dots, scopes, and just about any rail-mounted optic. The rifle also comes with adjustable iron sights, so you can shoot it right out of the box while you decide on glass.
Is the SU22CA just a .22 conversion of the SU16?
No, it is a standalone rifle designed around the .22 LR cartridge from the start, not a conversion kit. It does share the SU16's general layout and several parts, including the grip, sights, and the storage compartment stock, so many SU16 accessories carry over.
