EOTech G45 5X Magnifier with Switch-to-Side Mount G45.STS

Overview of the EOTech G45 5X Magnifier | G45.STS

The EOTech G45 5X Magnifier (G45.STS) gives you the reach to identify and engage targets far beyond the range of a standalone red dot. Built for precision shooters, this 5X optic pairs with any EOTECH holographic weapon sight and drops into place behind it on a standard rail. When you need a wide, unmagnified view for close work, the Switch-to-Side mount flips the G45 aside in an instant.

Law enforcement officers, military shooters, and serious gun enthusiasts rely on the G45.STS because it packs 5X power into a body nearly the same size and weight as the popular 3X G33. Tool-free windage and elevation adjustments, an adjustable diopter, and a wide field of view keep your sight picture sharp. The matte black, aluminum-bodied magnifier is waterproof to 33 feet and uses fog-resistant internal optics, so it stays clear when the weather turns.

Specifications

Compatibility

The G45 is designed to work with every EOTECH holographic weapon sight (HWS) model, including the 512, 518, 558, EXPS, and XPS series. It mounts on the rail directly behind your sight so the 1X dot and 5X magnified image stay aligned.

It fits any 1 inch Weaver or MIL-STD-1913 Picatinny rail, which makes it a natural pairing for AR-15 platform rifles and other flat-top carbines. Left-handed and right-handed shooters are both supported by the Switch-to-Side mount.

This is a magnifier, not a standalone optic. It is meant to boost an existing red dot or holographic sight and will not function as a primary sighting system on its own. Shooters who want a higher optical centerline can swap the included mount for aftermarket options.

Intended Users

Law enforcement officers and patrol rifle operators choose the G45 when they need to positively identify and engage threats at distance without giving up the speed of a 1X holographic sight up close. The fast Switch-to-Side transition fits the demands of duty use.

Military and tactical shooters value the rugged, waterproof build and the ability to extend the effective range of a dot-equipped carbine well past what a 3X magnifier allows.

Civilian gun enthusiasts, competitive shooters, and AR-15 builders also reach for the G45.STS to round out a serious EOTECH setup for range work, training, and long-range target identification.
