Key Features

3× magnification with Switch-To-Side mount

Flip the G33 out of the sight line instantly for 1× CQB shooting. Flip it back for 3× precision engagement. No tools, no delay — a single lever motion.

Keeps the 1 MOA dot crisp at 3×

EOTech’s holographic reticle stays sharp and consistent under magnification — a key advantage over LED red dots, which can bloom or distort at 3×.

Tool-free adjustments

Vertical and horizontal alignment adjustable without tools. Adjustable diopter for individual eye correction.

Compatible with all EOTech HWS models

Works with EXPS2, EXPS3, XPS2, XPS3, and 5-series HWS. Side buttons on the EXPS series remain accessible with the G33 mounted behind the sight.

About the EOTech G33 Magnifier

The EOTech G33 is a 3x red dot magnifier designed to pair seamlessly with EOTech holographic weapon sights. The defining feature of the G33 magnifier is its Switch-to-Side mount system — sometimes called a flip to side mount — which lets the operator quickly rotate the unit out of the sight line when magnification isn’t needed and rotate it back in when distance shooting calls for it. This design preserves the speed-of-acquisition advantage of the holographic sight at close range while giving you the option to engage targets at distance.

The G33 offers approximately 2.2 inches of eye relief, which is enough to use with full eye protection and tactical helmets without being so generous that the optic feels disconnected from the shooter. Because the EOTech G33 magnifier mounts behind the host sight on a standard Picatinny rail, it is compatible with EOTech XPS and EXPS series holographic sights as well as third-party red dots that share the same mounting envelope.
