The EOTech G43 is a compact 3x flip-to-side magnifier that extends the reach of EOTech holographic sights without weighing the rifle down. On its Switch-to-Side (STS) quick-detach mount it drops in behind your sight for magnified target ID, then swings aside instantly for 1x close-quarters speed.
Its smaller, lighter footprint than a 5x makes it ideal for nimble, space-conscious builds while still delivering a clear, crisp picture.
How It Compares
Need more magnification at distance? Step up to the EOTech G45 (5x). Compare all red dot sight magnifiers and pair with EOTech holographic sights from the wider EOTech range. Not sure 3x vs 5x? Read our magnifier guide.

Frequently Asked Questions
Which sights does the G43 fit?
EOTech EXPS and XPS holographic sights, plus other optics set at a compatible standard mounting height.
G43 (3x) or G45 (5x)?
The G43 is smaller and lighter with a forgiving eye box; the G45 reaches further at 5x. Choose 3x for general use, 5x for distance.
Does it have its own reticle?
No — it magnifies the reticle of the host holographic sight.
Can I flip it aside?
Yes — the STS mount swings it out of the way for 1x, or detaches entirely.
