The Ruger Precision Rimfire .22 WMR draws a generally positive response, with a few recurring concerns.

Many owners praise the rifle's accuracy, noting tight groups at both short and longer ranges. Build quality gets good marks too -- the construction feels solid and holds up over extended use.

The adjustable stock and trigger are frequently called out as genuine highlights. Being able to dial in length of pull and trigger feel matters for shooters who want a rifle that fits them rather than something they adapt to.

On the negative side, some users find the rifle heavier than expected for a rimfire, which shows up on long carry days. The price also comes up; not everyone agrees the cost over basic .22 options is justified. New shooters transitioning from semi-automatics sometimes mention a learning curve with the bolt-action operation. A handful of users note that aftermarket accessories are less plentiful than for more popular calibers.
