Firefield Diverge 3X Magnifier Manual (FF19023)
The Firefield Diverge 3x Magnifier is an excellent accessory to increasing the magnification of accompanying red dot sights for a greater engagement range. Able to mount on a Picatinny rail, the Diverge 3x boasts fully multi-coated optics and external windage and elevation adjustments to quickly align with your primary optic’s reticle for rapid-target acquisition. The Diverge 3x will improve your target identification for short and medium-range engagements, and its compact, lightweight design ensures it only complements your shooting system. Durable to its core, the Diverge 3x is made of hardy aluminum, IP66 water resistant and dust-proof, operates between temperatures of -22F to 160F and can withstand a maximum caliber of .308. When your primary optic needs a little extra ‘muscle’ to focus on those moving targets, the Firefield Diverge 3x Magnifier is the perfect solution.

and warnings. Follow safe firearm practices.
Mounting the flip-to-side mount to the magnifier is a very similar procedure to mounting scope rings onto a riflescope. The flip-to-side mount, however, uses a three screw clamping system mechanism to quickly mount the magnifier.
1. With provided hex key, unscrew the three socket head screws so that the clamp ring is loosened. It is not necessary to completely remove the screws.
2. Insert the magnifier into the flip-to-side mount and align the elevation adjustment so that it is pointing up.
3. Tighten the two socket head screws to 17 to 20 in. lbs of torque. DO NOT overtighten.
Next, the Firefield Diverge 3X Magnifier’s flip to side mount has an integrated weaver/ picatinny mount.
To mount, position the sight so the eyepiece faces the shooter, and the objective lens
(1) faces the weapon sight.
1. Loosen the mounting bolt (6) until the mount can fit over the attachment rail.
2. Attach the mount to the firearm’s rail. Make sure the recoil bolt is positioned in the groove of
3. When the mount is in place, tighten the mounting bolt (6). Make sure not to over tighten.
4. Check for proper eye relief and that you can see the full field of view through the magnifier while holding the rifle in a shooting position. If the full field of view cannot be obtained, mount the sight in the next forward or backwards groove space.
NOTE: To prevent injury from recoil, position the sight so that there is at least two inches of eye
relief once the scope is attached. The Diverge Magnifier provides 3” of eye relief so the sight can
be used safely.
The Firefield Diverge 3X Magnifier’s eyepiece (1) is designed to rotate to adjust for diopter. The diopter is the measurement of the eye’s curvature. People’s eyes are all curved differently. If the image does not appear clear, crisp, nor sharp, rotate the eyepiece until the image becomes clear and sharp. This adjustment should stay the same unless the magnifier’s operator changes.
OPERATING WINDAGE AND ELEVATION ADJUSTMENTS:
The Firefield Diverge 3X Magnifier has elevation and windage adjustments at the top and side
of the unit respectively. After mounting the magnifier behind a weapon sight, the reticle may
appear off center when looking through the magnifier. To center the reticle, windage and elevation adjustment should be made:
1. Using a flat head tool turn the elevation dial either way to adjust the field of view up or down.
2. Repeat this process for the windage adjustment dial until your reticle is centered in the field of view.
*Note: Changing the reticle position in the magnifier’s field of view does not affect point of impact of the weapon sight. Next, do not force further rotation of the elevation/windage adjustment when resistance is felt. This means the adjustment is at its end of travel, any forced rotation may damage the adjustment system.
OPERATING THE FLIP TO SIDE MOUNT:
The flip-to-side feature provides the ability to adjust to rapid changing environments.
When the shooter needs the 1x magnification of the weapon sight for close range
shooting, the flip-to-side mount can be flipped to the left of the weapon sight while in the
To engage the flip-to-side action:
1. With your hand grab the magnifier’s body using a pull up/push motion the magnifier will pivot to the left side. Continue to pivot the magnifier until a click sound is heard indicating it is secured in position.
2. To return the magnifier to its co-witness position, grab the magnifier’s body and with a pull up/push motion pivot the magnifier back to its original position. Continue to pivot the magnifier to its original position until a click sound is heard indicating the magnifier is secured in position.
Proper maintenance of the Firefield Diverge Magnifier is recommended to ensure longevity. It is recommended that when the sight becomes dirty that it is wiped down with a dry or slightly damp cloth. Blow dirt and debris off all optics and then clean lenses with a lens cleaning cloth. To remove oils or dried water spots, apply a small amount of denatured alcohol to a lens cloth or cotton swab. Clean the surface of the lens and let dry. Finally use your breath to clean the lens once more. No further maintenance is required. Do not attempt to disassemble any components of the magnifier. To ensure the flip action operates smoothly, apply a dry lubricant to the ball detents. DO NOT use an oily lubricant as this can attract dust and cause friction in the pivot and locking system.
Make sure your Firefield Diverge Magnifier is securely attached to your firearm before storing.
• Before handling the Firefield Diverge Magnifier read and understand the contents of your firearm’s manual, and the Sightmark manual. Follow all standard safety precautions and procedures during
firearm operation, even when the reflex sight is not in use.
• Avoid hitting or dropping the unit.
• ALWAYS check the chamber of your weapon is clear before mounting or dismounting the reflex sight.
• The reticle illumination should be tested during periods of non-use to make sure it is still operating
properly. Failure to follow standard firearm safety precautions and procedures, as well as the above
warnings, is dangerous and may result in serious injury, damage to property, or death.
Never ship back a product without getting proper authorization beforehand. Doing so could result in losing the product due to a multitude of reasons, i.e. sending it to the wrong address and other problems associated with unexpected packages.
It is difficult to pivot the mount’s flip-to-side action:
Slightly loosen each socket hex screw on the front and back of the magnifier mount. Follow
the instruction “Adjusting the tension of the flip-to-side action”.
The mount does not stay secured in the flipped position:
Slightly tighten each socket hex screw on the front and back of the magnifier mount. Follow the instruction “Adjusting the tension of the flip-to-side action”.
The reticle is blurry and not in focus:
Rotate the eyepiece to adjust the diopter adjustment until the reticle becomes clear and sharp. If the reticle remains fuzzy, this is a limitation of the reflex or red dot sight, not the magnifier. Some reflex/red dots use a conventional single lens system. Single lens systems have spherical aberrations which is an optical effect that occurs when light is reflected off the objective lens at different angles and does not converge at a single focal point. To the naked eye, the disparity between light rays in a single lens system is undetectable and washed out by light. When the reticle is viewed through a magnifier the imperfections are magnified resulting in a slightly blurry reticle. Some red dots may appear to have a tail or appear as an oval instead of circle while crosshair designs may appear slightly fuzzy. This is not a defect with the magnifier, but a performance limitation of the weapon sight’s ability to accurately collimate light.
