USER’S MANUAL FOR G33™

Rev B

For use with G33 Magnifiers or HHS Systems

INTRODUCTION

Thank you for purchasing L-3 EOTech’s new Generation III 3X magnifier. These magnifiers offer users of the Holographic Weapon Sight (all models) the additional advantage of vastly improved target recognition and increased lethality at medium range distances. The new Switch to Side (STS) mount allows the user the ability to engage the enemy with confidence in a

Close Quarters Battle (CQB) situation or at distances out to 600 meters or more. This user manual describes the features of the

L-3 EOTech Magnifiers and provides information on their use and maintenance. Please read the instructions carefully before mounting and using the magnifiers. Always practice proper firearm safety.

The G33 magnifier is designed to be used behind an L-3 EOTech Holographic Weapon Sight (HWS). The magnifier can be mounted directly behind the HWS. Simply switch the magnifier out of the way and operate the sight. When used with HWS models 556, 517, EXPS or 516 HWS (with side button interface) the user can easily operate the sight even with the magnifier in the locked position.

Positioning the Reticle:

Once the magnifier is installed properly behind the HWS, it may be necessary to re-zero the sight. This may be due to the shooter’s ability to see the target and Point of Impact (POI) more accurately than without the magnifier. Re-zeroing the sight will prevent a perceived shift in POI when going from no magnification to magnification.

OPTIC CONFIGURATION

The L-3 EOTech Holographic Weapon Sight (HWS) product line has two different heights above the rail based on user preference. For this reason, the magnifier does not come preassembled to the mount.

It is user configurable based on the specific model HWS it will be mounted behind. The 7mm riser, included, may be required to align the magnifier optical axis with the sight. Only HWS models with side buttons or quick detach levers require the use of the riser. For all other HWS models, the riser should not be used.

The magnifier system can be configured to switch to the left or to the right based on shooting preference. Typically, right handed shooters prefer the mount to switch to the left, and left handed shooters to the right.

To configure your HWS you will need a screwdriver (not included). If the spacer is not used, the shorter screws should be selected. The longer screws are used with the spacer only. If the spacer is being used, place the spacer on the optic mounting interface. Open the STS mount. Position the mount on the optic mount interface (or riser) so it opens either to the left or right (based on preference). Insert each screw through the components, and tighten securely.

ADJUSTABLE DIOPTER

The G33 optic includes an adjustable diopter that allows the user to customize the focus to their particular vision. This feature ensures a crisp, clean aiming dot for more precision and shot placement. To adjust, simply grasp the diopter with the thumb and fore finger and turn either clockwise or counter-clockwise until a clear sight picture is achieved.

After zeroing or re-zeroing the sight, it may be necessary to reposition the reticle image into the center of the magnifier window. This is aesthetic in nature and has no affect on the sight’s zero. Turn the horizontal and vertical adjustments on the top or side of the magnifier by hand, with a coin or a flat head screwdriver to reposition reticle to the desired position.

Switch operation:

To switch the magnifier to the side, simply push the optic to the right or left, depending on how it is mounted. To close the mount, push the magnifier back into its original position until a hard stop is achieved.
