Owners of the Tristar KR-22 appreciate the two included magazines right out of the box, which is seen as good value for the price. The olive drab finish gives it a practical, subdued look that appeals to buyers who want a working rimfire without flashy aesthetics.

The threaded barrel is a popular feature among owners who run a suppressor or want the option later. Reliability with standard-velocity .22 LR gets mixed reviews; most report consistent cycling but a subset note occasional failures to feed with certain ammunition. High-velocity loads tend to run more reliably according to owner feedback.

The KR-22 sits in an interesting spot: it attracts buyers looking for an affordable, functional .22 semi-auto without a lot of extras. Trigger feel is the most common criticism, described as gritty or heavy for a rimfire, but owners who upgrade or simply adapt tend to be happy with the platform overall.
