New standards. Timeless features. The TM22 is built for all ages, all types of scenarios. Comes stock with a top-rail for optics, right-handed controls but converts from right-handed to left-handed if desired. This model ships with a standard Picatinny top rail for mounting the optic of your choice. Note: The TM22-S-18 will not accept extended 15-round or 25-round TM22 magazines, as they are missing the notch required to lock into the magazine well.
