How to Choose

Pick the EXPS3 if:

You use iron backup sights and need Lower 1/3 Co-Witness for quick aiming transitions.
You prefer side buttons, which are easy to locate and press even with gloves or in high-stress situations.
Weight and rail space are not major concerns for you.

Pick the XPS3 if:

You prioritize ultra-light weight and a compact profile, and need extra rail space for night vision mounts, magnifiers (e.g. G33) or large rear sights.
Your rifle is fitted with iron sights for Absolute Co-Witness, or you do not rely on iron sights as backups.
You mainly use the sight for Close Quarters Battle (CQB) and want a streamlined setup.

Shared Specifications

MAGNIFIER G43:
The G43 Magnifier is a miniaturized version of our battle-tested G33 Magnifier, making it one of the most compact and lightweight magnifiers available. The mount provides fast transitioning from 3X to 1X and comes with a 7mm spacer to properly adapt to any HWS model.

MAGNIFIER G33:
The G33 Magnifier is the choice magnifier of USSOCOM. Compact, lightweight, and easily mounts to a picatinny rail. The mount provides fast transitioning from 3X to 1X, and the optic offers tool-free vertical and horizontal adjustments, larger field-of-view, and an adjustable diopter for improved precision focus.

The G45 5X Magnifier has the similar weight and dimensional properties as the existing G33 Magnifier, but with an additional 2X magnification for precision aiming at greater distances. The mount quickly transitions from 5X to 1X on the fly and the optic offers tool free vertical and horizontal adjustments with a large field-of-view.
