A 1x red dot sight is quick and clear. But as distances grow or details become more important, the extra magnification is often missing. A 3x magnifier is exactly the pragmatic middle ground: more image when needed, otherwise the setup stays fast.

The EOTECH G33.STS Magnifier is the classic 3x magnifier for compatible EOTECH red dot sight setups. With switch-to-side mounting, it can be flipped to the side when you want to work without magnification again.

This product page refers to the STS version. The magnifier is delivered in the chosen color with switch-to-side mounting, unless explicitly stated otherwise in the specific variant.

Key Features


3x magnification: more detail recognition while maintaining a well-controlled field of view.

Switch-to-side mounting: quick switch between 1x use and magnified sight picture.

Compatible with EOTECH red dot sight models: designed by the manufacturer for all EOTECH red dot sight models.

Quick-detach attachment: mounts on 1-inch Weaver or MIL-STD-1913 rail according to manufacturer.

Tool-free height and windage adjustment: facilitates precise alignment behind the red dot sight.

Eye relief 55.9 mm: important for correct positioning behind the primary optic.

Black or Tan: color variant selectable to match your setup.

Our Assessment
The G33.STS is the balanced EOTECH magnifier for many setups: not as strong magnification as the G45, but fast, clear, and very practical with 3x. It fits well if you want to make a red dot sight system more flexible without switching directly to a scope or LPVO.

Compared to the G43, the G33 is a bit more classic in design. The G43 is more compact, the G33 remains the familiar 3x option for users looking for a robust, proven layout with good handling. Ultimately, it’s not just the magnification that matters, but whether eye relief, mounting height, and rail space fit your setup.

Black-Raptor short summary:
Buy if you want a classic 3x magnifier with STS mounting for your EOTECH red dot sight setup and a good mix of magnification, overview, and handling.
Don’t buy if you want maximum 5x magnification, an ultra-compact magnifier setup, or a classic scope with its own reticle.

Practical Tip: Adjust height and eye relief carefully
Magnifier and red dot sight must not only be on the same rail but also ergonomically fit together. Before final tightening, check if you get a full picture without straining your neck and if the magnifier moves freely in both positions.

Important Classification Before Purchase
The G33.STS is not a standalone optic. It magnifies the sight picture of a suitable primary optic. If you want a real scope with its own reticle, click adjustment, and range logic, a magnifier is not the right solution.

When choosing between G33, G43, and G45, the G33 is the classic 3x variant. The G43 is more compact, the G45 offers stronger magnification. For many range and training uses, 3x remains the most comfortable compromise.
