Frequently Asked Questions
Does the Kel-Tec SU-22 accept Ruger 10/22 magazines?
Yes — one of the most popular features of the SU-22 is its compatibility with standard Ruger 10/22 rotary and aftermarket magazines. This gives shooters a wide range of capacity and brand options beyond the included 15-round magazine, making it easy and affordable to keep extra mags on hand for range days.
How does the underfold stock work, and does it affect shooting comfort?
The SU-22's underfold stock rotates downward and forward beneath the receiver, dramatically reducing the overall length of the rifle for storage and transport. When deployed, the stock locks firmly in place and provides a stable, comfortable cheek weld for accurate shooting. Most users find the transition between folded and unfolded positions quick and intuitive.
What types of .22 LR ammunition work best in the SU-22?
The Kel-Tec SU-22 is designed to function reliably with standard and high-velocity .22 LR loads. Most shooters report excellent results with quality high-velocity rounds from brands like CCI, Federal, and Remington. As with most semi-automatic .22 LR firearms, performance with subsonic or bulk economy ammunition can vary, so it's worth testing a few loads to find what cycles most reliably in your specific rifle.
