Brand Breakdown

EOTech at 30.8% combined leads with the G45 5x magnifier. Designed to pair with EOTech holographics, the G45 offers best-in-class glass clarity at 5x. Vortex at 10.7% offers the Micro 3x, a compact and affordable magnifier. SightMark at 8.8% is the budget entry with the T-3 3x. Sig Sauer at 11.1% combined (Juliet3 QR 6.3%, Juliet 3 Micro FDE 4.8%) offers both standard and micro-sized magnifiers.

If you are running an EOTech holographic, the G45 at 23.7% is the natural pairing. But you do not need to match brands. A Vortex Micro 3x behind an EOTech XPS2 works perfectly fine and saves money.

  1. Budget (Under $150): SightMark T-3 3x. Functional magnification for the price.
  2. Mid ($150-$350): Vortex Micro 3x or Sig Juliet 3 Micro. Compact, quality glass, good mounts.
  3. Premium ($500+): EOTech G45 5X. Best glass, 5x magnification, flip-to-side mount included.

Frequently Asked Questions

The EOTech G45 5X Black leads at 23.7% of all magnifier selections. It provides 5x magnification and is designed to pair with EOTech holographic sights, though it works with any red dot.
3x is the traditional choice and works well for 100-300 yard shots. 5x (like the EOTech G45 at 23.7%) extends that to 400+ yards. 3x magnifiers are typically lighter and more compact. Most builders go 3x unless they need the extra reach.
Yes. Magnifiers work behind any red dot or holographic sight. They magnify whatever the dot projects onto the target. The most popular pairing is EOTech holographic + EOTech G45 magnifier, but Vortex, Sig, and other magnifiers work cross-brand.
