Description
The EOTECH G43 is a compact 3x flip-to-side magnifier built to run behind an EOTECH holographic weapon sight. It does the job every magnifier on a fighting rifle is there to do: keep the speed and both-eyes-open simplicity of your holographic sight up close, then flip the G43 into place when you need 3x to identify or engage a target at medium range. Push it to the side and you're instantly back to an unmagnified 1x sight picture.
The G43's calling card is its compact size. It's EOTECH's smallest-profile 3x magnifier, so it adds magnification on demand without a lot of bulk hanging off the rail behind your sight. It mounts on the included Switch-to-Side (STS) quick-detach mount to any 1" Weaver or MIL-STD-1913 rail, and the locking QD lever lets you remove it entirely when you want to run light. It works for both left- and right-handed shooters.
Setup is tool-free: windage and elevation adjust without tools to align the magnified image with your holographic reticle, and the adjustable diopter focuses the image sharp to your eye. Eye relief is 2.6", the optics are fog-resistant, and the unit is waterproof to 33 feet, so it holds up to weather and immersion.
It's compatible with all EOTECH HWS models, and pairs especially well with the side-button sights like the EXPS3, where you can still reach the controls with the magnifier mounted behind it. Browse the rest of our optics and magnifiers here.
G43 vs G33 vs G45
EOTECH makes three magnifiers, and the honest breakdown helps you pick. The G43 is the most compact 3x option. The G33 is also 3x and is the long-proven EOTECH standard; because of its longer body, it generally offers more comfortable eye relief than the G43, and the weight difference between the two is minimal. The G45 is 5x in nearly the same size as the G33, for shooters who want more reach. So: pick the G43 if compact size is your priority, the G33 if you want the proven 3x with the best eye relief, or the G45 if you want maximum magnification.
Pair It With a Sight
A magnifier needs a holographic sight in front of it. The EOTECH EXPS3 is the night-vision-capable flagship and a natural match thanks to its side-button controls. For glare protection on the sight up front, the CovertArms HWS ARD is a honeycomb killflash cut for the EOTECH window.

FAQ
What does a magnifier do for my EOTECH?
It sits behind your holographic sight and adds 3x magnification when you flip it into place, so you can identify and engage targets at medium range. Flip it to the side and you're back to your normal 1x sight picture for close-range speed.
What's the difference between the G43 and the G33?
Both are 3x. The G43 is more compact, while the G33 has a longer body that generally gives more comfortable eye relief, and the weight difference between them is small. Choose the G43 if compactness matters most; choose the G33 for the proven standard with better eye relief.
Does it come with a mount?
Yes. It includes the Switch-to-Side (STS) quick-detach mount, which fits 1" Weaver and MIL-STD-1913 rails and lets you flip the magnifier aside or remove it entirely.
Will it work with my EOTECH sight?
It's compatible with all EOTECH HWS models, and works particularly well with side-button sights like the EXPS3, where you can still reach the controls with the magnifier mounted.
How do I line it up with my sight?
Tool-free windage and elevation adjustments center the magnified image on your holographic reticle, and the adjustable diopter focuses the image to your eye. No tools required.
