Overview

The EOTech EXPS3 + G33 Magnifier Combo pairs EOTech's EXPS3 holographic weapon sight with their G33 3x magnifier in a single package. This pairing delivers versatility for shooters who need both close-quarters speed and mid-range precision without compromising either capability. Adopted by special operations units, law enforcement SWAT teams, and competitive 3-gun shooters, this combo has seen widespread use across shooting disciplines.

The EXPS3-0 provides EOTech's signature 68 MOA ring with 1 MOA center dot, enabling lightning-fast target acquisition in close quarters while the precise center dot maintains accuracy beyond 200 yards. When extended range precision is required, the G33 magnifier flips into position behind the holographic sight, instantly transforming the system into a 3x magnified optic effective to 300+ yards. The magnifier's Switch-to-Side (STS) mount allows instant transition back to 1x by flipping the magnifier out of the optical path—no tools, no adjustment, just pure speed.

Buyers should be aware of EOTech's quality history: in 2015, L-3 Communications paid $25.6 million to settle a lawsuit for knowingly selling defective optics with thermal drift issues to the military since 2006. Post-2016 units show improved thermal performance comparable to competitors, though some users continue to report delamination issues. The EXPS3 features 30 brightness settings (20 daylight + 10 NVD), quick-detach lever mount, and submersibility to 33 feet. The G33 magnifier delivers edge-to-edge clarity through its multi-coated glass and features its own QD mount for tool-free removal. At $1,349 for the combo, this pairing costs less than purchasing the components separately.
