Description
EOTech G43 3x Magnifier with Switch-to-Side mount is the short answer to a crowded rail. It gives the same 3x as the G33 from a noticeably shorter body, so a sight, magnifier and back-up irons can all live on the same top rail without a fight. The Switch-to-Side mount swings it clear for unmagnified shooting and pivots to either side.
How It Compares
Prefer the classic full-length 3x? The G33. Want more reach? The 5x G45. Mount already fitted? Take the G43 no-mount. Compare the full range of magnifiers, or read choosing a red dot magnifier.
Also available in: Tan.

- Rails already crowded with sight and back-up irons

Product FAQs
Should I get the G43 or the G33?
Both give 3x magnification, so choose on the space you have behind the sight. The EOTech G43.STS is the shorter, lighter package while the G33 is the standard all-rounder.
Does the G43.STS come off the rail quickly?
Yes, the Switch-to-Side mount on the EOTech G43.STS has a locking adjustable quick-detach lever. Day to day you will just swing it aside rather than remove it.
What sights does the EOTech G43 work behind?
The EOTech G43.STS works behind EOTech holographic weapon sights and standard-height red dot sights.
Can I sharpen the G43 image for my eyes?
Yes, the diopter on the EOTech G43.STS adjusts so you can bring the image into focus for your eyesight.
What magnification does the G43 with STS mount give?
The EOTech G43.STS gives 3x optical magnification from a compact body.
Which side does the G43 STS mount flip to?
Either side. The Switch-to-Side mount on the EOTech G43.STS is ambidextrous, suiting left- or right-handed shooters.
Can I zero the G43 magnifier itself?
Yes, the EOTech G43.STS has tool-free windage and elevation adjustment so the magnified image lines up with your sight.
How big and heavy is the G43 with STS mount?
The EOTech G43.STS measures 3.1 x 2.3 x 3.3 in and weighs 11.3 oz.
Is there a magnifier with more reach than the G43?
Yes, the 5x EOTech G45 offers more reach than the 3x G43.STS.
What if I already have a mount on my rifle?
If a mount is already fitted, the EOTech G43 no-mount version supplies the optic alone. This G43.STS listing includes the Switch-to-Side mount.
What is in the box with the EOTech G43.STS?
The box contains the EOTech G43 magnifier and a Switch-to-Side quick-detach mount.
Does the G43 with STS mount come in another colour?
Yes, the EOTech G43 with STS mount is also offered in Tan alongside this Black version.
How long does UK delivery take on the G43.STS?
