Owners of the TM22 tend to appreciate the combination of lever-action styling with the .22 LR chambering. It draws in shooters who want a fun rimfire option with a classic action type, and the threaded barrel is a frequently mentioned plus for those running suppressed.

The lever throw and cycling smoothness get mixed reactions. Some find it crisp after a break-in period, while others note it requires more deliberate operation than a semi-auto rimfire. Fit and finish comments are generally positive for the price point, though a few owners flag minor fit issues on the stock-to-receiver junction.

Value is a common talking point. The TM22 sits in a niche between budget rimfires and more expensive lever guns, and buyers who wanted a threaded-barrel lever-action rimfire without spending significantly more tend to be satisfied with the trade-offs.
