The EOTech G33 Magnifier with STS Mount is a 3x magnifier supplied on EOTech's Switch-to-Side (STS) quick-detach mount, with approximately 2.2 in (56 mm) of eye relief, a length of approximately 3.9 in (99 mm) and a weight of approximately 10.6 oz (301 g).
A magnifier sits behind a holographic or red dot sight and multiplies whatever that sight already shows you. The STS mount is what makes it practical: one push and the magnifier swings out to the side, so you drop straight back to 1x without removing anything or losing zero.
Finish: Black — also sold as the G33 3x magnifier with STS mount in Tan, and without a mount as the G33 3x magnifier, no mount.
How It Compares
The G33 is the shortest-eye-relief 3x in the range. The G43 is also 3x but shorter overall at approximately 3.1 in; the G45 steps up to 5x. Pair it with an EXPS3-0 holographic weapon sight, or buy the pair together as the HHS VIII hybrid sight system. Browse all red dot magnifiers and read how to choose a magnifier.
