Steiner TM3X is a compact 3x magnifier designed for use with red dot sights. The model is equipped with a Picatinny rail mount and a mechanism allowing the magnifier to flip to the right and left side, making it easier to switch quickly between magnified and unmagnified observation. The design combines compact dimensions with solid workmanship and durability suited to demanding operating conditions.

The optical system offers 3x magnification, an 18 mm objective lens diameter, 92% light transmission, a field of view of 11 m at 100 m, and 56 mm eye relief. The magnifier features diopter compensation in the range from -2 dpt to +2 dpt, is nitrogen filled, waterproof to 20 m, and shock resistant up to 900 G. This makes it well suited as an addition to a red dot sight setup in applications requiring a quick change in aiming method.
