INSTALLING THE BATTERY:
The Firefield Impulse 1x30 Red Dot Sight is powered by a single CR123A battery. Should the reticle
illumination grow dim or fail to illuminate, the battery needs to be replaced.
To install a new battery:
1. Unscrew the battery cap (6) counterclockwise.
2. Insert the new battery into the battery compartment (5) with the negative (-) side inserted first.
3. Screw the battery cap on clockwise until firmly secure. Do not over tighten.
To turn the unit on:
1. Press and release the on/off control (7).
To turn the unit off:
1. Press and hold the on/off control for 3 seconds.
The Firefield Impulse 1x30 Red Dot Sight offers 6 brightness settings. Settings 1 and 2 are best
for low light, indoor environments while 3-6 are best for outdoor environments.
To adjust the brightness:
1. Press the appropriate up or down arrow (8) to adjust the brightness of the dot.
2. To increase brightness press the up arrow.
3. To decrease brightness press the down arrow
The Firefield Impulse 1x30 Red Dot Sight is designed to mount to picatinny rails. For safety it is
best to have at least three to four inches of eye relief.
1. Loosen the mounting hex nut (12) on the mount. Attach the sight to the firearm’s rail with
the objective lens facing toward the muzzle and the eyepiece toward the user.
2. Make sure the recoil bolt is positioned in the groove of the rail and the unit is fully seated on
3. Tighten the hex nut to 35 to 45 in/lbs of torque using the hex wrench. Do not
OPERATING WINDAGE AND ELEVATION ADJUSTMENTS:
The Firefield Impulse 1x30 Red Dot Sight has built-in windage and elevation adjustments (2, 3) with
audible clicks. The click value is 1 MOA, so each click moves the point of impact 1” at 100 yards,
½” at 50 yards, and ¼” at 25 yards. In order to make windage and elevation adjustments:
1. Unscrew the dial covers.
2. Use a coin or flathead screwdriver to make adjustments or “clicks”
3. Turn the adjustments in the appropriate direction needed to change the point-of-impact as
indicated by the “UP” and “R” (left) arrows marked on the adjustments.
4. For elevation adjustment, turn the adjustment counter-clockwise to adjust the bullet’s point of
impact up. Turn the adjustment clockwise to adjust the bullet’s point of impact down. For windage
adjustments, turn the adjustment counter-clockwise to adjust the bullet’s point of impact right. Turn the adjustment clockwise to adjust the bullet’s point of impact left.
BORESIGHTING AND SIGHTING IN:
Boresighting and test firing should be performed safely on a firing range. Laser boresights are a
quick and accurate method for sighting in. Below is listed the traditional method of boresighting
and works best when the unit is mounted on a rest:
1. When mounting the sight on a bolt action rifle, remove the bolt; or when mounting to
a semi-automatic rifle, disassemble the rifle until there is a straight line of sight through the
2. Use a target at least twenty yards to fifty yards away when sighting in the sight. Look through
the bore of the weapon and locate the bull’s-eye of the target.
3. Sight in the target through the bore and then make windage and elevation adjustments
(see “Operating Windage and Elevation Adjustments” for instructions) to the red dot sight until the reticle is centered on the bullseye.
To verify the sight is accurately sighted in, always fire a three-shot test group at 50 or 100 yards
preferably using the same ammo manufacturer, grain, and lot number.
4. After firing a group use the center of this grouping and make the necessary amount of
adjustments to the elevation and windage adjustments to move your firearm’s grouping to the
center of the target.
5. Again fire a three-shot test group, and use the center of the group to determine final
OPERATING THE INTEGRATED LASER:
The built-in 5mW red laser is used for target acquisition in close range, rapid changing
environments. The laser has built-in windage and elevation adjustments (11) that allow the laser to
be accurately sighted in with your rifle. To operate the laser:
1. Locate the red laser on/off switch (9).
2. Push the button to turn the laser on.
3. Push the button again to turn the laser off.
To zero the laser:
1. Unscrew the dial covers.
2. Use a coin or flathead screwdriver to make adjustments. Note that the adjustments do not have clicks, but are a continuous adjustment system. Zero the
laser to your reticle at the same zero distance, or zero the laser at a secondary zero distance.
Warning: NEVER point the laser designator directly at, or into, someone’s eye. This may cause
damage to the eye, or blindness. Avoid looking directly into the laser. Avoid shining the laser into
mirrors or other reflective surfaces.
Note: due to visual restrictions of 5mW red lasers at greater distances in daylight, the most effective application is for close range/ CQB scenarios.
Shooters should evaluate the range targets are acquired most frequently and sight the laser to their firearm’s point of impact at that range.
Proper maintenance of the Firefield Impulse 1x30 Red Dot Sight 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 scope.
Make sure that your Firefield Impulse 1x30 Red Dot Sight is securely attached to your rifle before
storing, and be sure that the reticle illumination is turned off. Cover with the included lens covers.
Remove the batteries if the unit will be stored for an extended period of time.
WARNING: Before handling the Firefield Impulse 1x30 Red Dot Sight read and understand the contents of your
firearm’s manual, and the Firefield 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 that the chamber of your weapon is clear before mounting or dismounting the
red dot 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.
Proper authorization is required before shipping any product back to Firefield. Failure to obtain
authorization could result in your product being returned to the wrong address, lost, or damaged.
Firefield is not liable for products returned without authorization.
If the sight does not hold zero:
1. Verify the sight is mounted securely to the rifle. If the sight can be shifted in any direction, re-tighten the mounting hex nut according to the mounting instructions but do not over tighten. The
sight will need to be re-zeroed afterwards.
2. Be sure to use factory-loaded ammunition of the same bullet type, weight, and, preferably lot
number when sighting in.
The reticle does not illuminate:
1. Check that the battery is in working order and that the polarity of the battery is correct.
2. Check that there is no residue, film, or corrosion on the battery contacts that may be
preventing the reticle from illuminating.
3. Make sure the unit is not set on a night vision mode.
The reticle is blurry and not in focus:
1. Decrease the brightness level of the reticle. The halo or fuzzy appearance is caused by excess
illumination than is required for the current environment the sight is being used in.
2. Make sure the eyepiece lens is clean and does not have any film, fingerprints, or debris covering
the surface. Blow off any debris or dirt covering the lens. Use a lens cloth or q-tip dipped in
alcohol to remove any film or fingerprints.
3. If you are testing the product at a close range, 5 yards or less, to verify its on/off operation the
eye will accommodate and focus either on the sight’s reticle or the target you are observing not
both. Test the product beyond 5 yards and focus your eye on the target, then the reticle and
target should be in focus.
The reticle illumination turns off while firing:
1. Tighten the battery cap with a coin or flathead screw driver so the cap is fully seated.
