The Ruger American Rimfire .22 WMR gets generally positive marks, with a few recurring criticisms worth knowing before buying.

Most owners praise the bolt action for cycling smoothly and the overall build quality as solid. Accuracy consistently comes up as a strength, both at the range and on small game. The adjustable Ruger Marksman trigger gets specific mention as a meaningful feature, and the lightweight build is appreciated by anyone carrying it in the field for any length of time.

On the critical side, the 9-round capacity is the most common complaint from shooters who prefer higher-capacity options. Price is occasionally flagged as a concern, though most find it justified given the performance. A small number of users have reported feeding or extraction issues on certain units, though these appear to be outliers rather than a pattern.

Overall, the rifle's combination of accuracy, adjustability, and manageable weight makes it a solid rimfire option for hunters and target shooters alike.
