Who This Is For

The EOTech G45 STS Tan is purpose-built for AR-platform and MSR shooters who rely on an EOTech HWS for close-quarters engagement but need the versatility to reach out to 300–600 yards with confidence.

Frequently Asked Questions

Is the EOTech G45 compatible with non-EOTech red dot sights?

The G45 is engineered and optimized specifically for use with EOTech Holographic Weapon Sights (HWS). While it may physically mount behind other optics, EOTech designs and warranties the G45 for use with their own HWS product line to ensure proper eye relief, reticle alignment, and performance. For best results, pair it with an EOTech HWS such as the EXPS3 or XPS2 series.

How does the Switch-to-Side (STS) mount work, and how fast is the transition?

The STS mount allows you to pivot the G45 magnifier out to the side of your rifle in a single, fluid motion — no tools required. This lets you instantly switch from a magnified 5x view to an unmagnified 1x holographic sight picture for close-quarters engagement, then swing it back into line for distance shots. The transition takes under a second with practice, making it one of the fastest magnifier systems available for dynamic shooting scenarios.

What is the advantage of 5x magnification over the EOTech G33 (3x) magnifier?

The EOTech G45 offers 5x magnification compared to the G33's 3x, giving you a significantly extended effective engagement range — ideal for targets at 300 yards and beyond. Despite the added power, EOTech engineered the G45 to maintain similar weight and dimensions to the G33, so you won't feel a significant change in rifle balance. If you regularly engage targets at distance or participate in competitions with longer stages, the G45's extra magnification provides a meaningful tactical advantage.
