How to Change the EPS Carry Reticle Without Damage

To change the reticle on a Holosun EPS Carry MRS, make sure the optic is on, then press and hold the “−” brightness button for three seconds. Each hold cycles through the 2 MOA dot inside a 32 MOA circle, the 2 MOA dot alone, and the 32 MOA circle alone, in that order, according to the Holosun EPS/EPS Carry User’s Manual. This works only on model designations ending in MRS; EPS Carry models ending in -2 or -6 have a fixed dot and cannot cycle reticles.

That distinction solves most failed attempts. I approach it as I would a suspect race split: establish which device produced the number before interpreting the number. Here, the model code is the collection condition. A long button press cannot uncover a reticle that the emitter was never built to produce.

Keep the firearm unloaded and cleared while learning the controls. Remove the magazine, verify an empty chamber, and maintain a safe direction. Holosun puts that instruction ahead of installation and battery replacement in its manual; it is sensible whenever attention will be on two small buttons rather than the firearm’s status.

How do you change the reticle on an EPS Carry MRS?

The reticle change is an electronic setting. It requires no tool, no removal from the slide, and no contact with the windage or elevation adjustments.

1. Unload and clear the firearm. Work in good light, with the muzzle kept in a safe direction. Confirm the exact model marking on the optic or its box includes MRS, such as `EPS-CARRY-RD-MRS`.
2. Turn on the sight. Briefly press either the “+” or “−” button. Holosun’s manual says a momentary press of either brightness control powers the optic on.
3. Hold the “−” button for three seconds. Release it after the reticle changes. Do not press both buttons, because that command turns the optic and its motion sensor off.
4. Repeat one full hold when needed. The documented order is circle-dot, dot only, then circle only. Stop when the sight picture you want appears.

One deliberate hold is better than several rapid stabs. A short press on “−” lowers brightness; it does not select another reticle. If the image merely grows dimmer, the input was too short. If the sight shuts off, both buttons were pressed together.

The 32 MOA circle includes four positioning marks around a centered 2 MOA dot. Holosun’s manual says the circle represents approximately 32 inches at 100 yards, or 81 centimeters at 100 meters. Those are angular dimensions, so the apparent coverage changes with distance even though the reticle’s angular size remains 32 MOA.

Which EPS Carry models can switch reticles?

Holosun uses the suffix to separate selectable and fixed reticles. The current Holosun product specifications list red (`RD`), green (`GR`), and gold (`GD`) versions; the color is fixed at manufacture. MRS changes the displayed geometry. It does not change a red emitter into green or gold.

| EPS Carry family | Example model designation | Reticle supplied | Can the “−” button cycle it? | |---|---|---|---| | Multi-Reticle System | `EPS-CARRY-RD-MRS` | 2 MOA dot, 32 MOA circle, or both together | Yes, with a three-second hold | | 2 MOA single-reticle | `EPS-CARRY-RD-2` | 2 MOA dot only | No | | 6 MOA single-reticle | `EPS-CARRY-RD-6` | 6 MOA dot only | No |

The corresponding `GR` and `GD` model families follow the same naming pattern on Holosun’s current product pages. A `GR-MRS`, for example, offers the same three shapes in green. An `RD-6` gives one 6 MOA red dot. The separate 2 MOA and 6 MOA products are choices made at purchase, not settings hidden behind another hold duration.

This is where loose retailer language causes trouble. “EPS Carry has multiple reticles” is true of the MRS variants and false for the family as a whole. Read the complete designation, including the final characters. If the housing says `EPS-CARRY-GR-2`, a three-second minus hold will only continue acting on the available brightness control; there is no circle in that model to display.

Why is an EPS Carry MRS not cycling reticles?

Begin with the model marking, then test the control state. That order costs nothing and prevents a settings problem from turning into a screwdriver problem.

• If the designation lacks `MRS`, stop troubleshooting the button sequence. The `-2` and `-6` versions are single-reticle optics.
• If ordinary brightness taps also produce no response, Lockout Mode may be active. Hold “+” for three seconds until the LED blinks once. The Holosun manual says this deactivates lockout and returns a solar model to Auto Mode or a non-solar model to Manual Mode. Then try the three-second “−” hold again.
• If a tap changes brightness but a hold does not change shape, time a clean three seconds and release fully. Keep your other finger away from “+”; pressing both controls is the power-off command.
• If the display is absent or slowly blinking, inspect the battery condition. Holosun specifies one 3-volt CR1620 lithium coin cell and uses a slow reticle blink as its low-voltage warning.

A single blink after a long “+” press is a mode confirmation. A continuing slow blink is the battery warning. Counting the pattern matters more than calling every blink an error.

If the model is MRS, the battery is sound, lockout is released, and repeated clean holds still do nothing, stop there. Prying a button, opening the sealed housing, or turning adjustment turrets cannot repair an electronic selection fault. Holosun’s manual says dismantling the optic voids the warranty; use the manufacturer’s support process instead.

Which button changes each Holosun EPS Carry setting?

The two controls share several jobs, and duration changes the command. This compact map comes from the sight-operation section of Holosun’s EPS/EPS Carry manual.

| Input | Result | |---|---| | Brief press on either button while off | Powers the sight on | | Brief press on “+” or “−” while on | Raises or lowers brightness | | Hold “−” for three seconds | Cycles reticles on MRS models only | | Hold “+” for three seconds | Changes operating mode or enters/exits Lockout Mode; one blink confirms the change | | Hold “+” for 10 seconds | Opens the sleep-timer adjustment | | Press “+” and “−” together | Powers off the sight and motion sensor; in the timer menu, saves the selection and powers off |

There is a labeling conflict inside the manual worth recording. Its operating-mode overview says “minus (+),” pairing the wrong word with the plus symbol. The detailed instructions immediately below repeatedly assign “+” to Manual and Lockout modes, while the separate MRS section assigns “−” to reticle selection. The symbol and detailed steps agree; this guide follows them.

In Manual Mode, Holosun provides 12 brightness levels. The manual identifies levels 1 through 4 as night-vision compatible and level 12 as the brightest, which leaves eight daylight levels. Current EPS Carry product specifications report the same split as “8 Daylight & 4 NV.” Brightness, operating mode, sleep delay, and reticle shape are four distinct variables. Changing one is poor evidence that another has changed.

Solar-equipped MRS models add Auto Mode. Their sensor adjusts reticle brightness with ambient light, while the battery supplies power when the solar cell cannot drive the reticle alone. A user watching brightness move in Auto Mode may think the minus hold failed, especially when the 32 MOA circle is faint against a bright background. Check the shape under stable lighting before repeating the input.

How do you change the EPS Carry Shake Awake setting?

Shake Awake controls when the illuminated reticle sleeps after the optic stops moving. The factory default is 10 minutes. Holosun provides four timer choices: 10 minutes, 1 hour, 12 hours, and OFF.

Hold “+” for 10 seconds to enter the timer menu. Briefly press either button to move among the choices and count the confirmation blinks: one blink selects 10 minutes, two select 1 hour, three select 12 hours, and four select OFF. Press “+” and “−” simultaneously to save the selection and power down the sight.

OFF in this menu disables sleep mode, so the optic will not shut its reticle down after inactivity. It also removes the battery-saving job that Shake Awake performs. To turn off a Holosun EPS Carry immediately, press both brightness buttons together; Holosun says this powers down both the sight and the motion sensor. A momentary press on either button turns the sight on again.

The timer and the reticle use different long presses for a reason worth memorizing. Three seconds on minus changes an MRS shape. Ten seconds on plus enters the sleep setting. Mixing them will alter another setting, yet it gives no justification for loosening the optic or touching its zero.

What do the battery and brightness numbers actually mean?

Holosun claims that a high-quality CR1620 battery can power the EPS/EPS Carry for up to 50,000 hours with the dot at brightness setting 6. The bold part is the measurement condition. The manual does not promise 50,000 hours for every brightness level, reticle pattern, temperature, battery brand, or sleep-timer choice.

That qualifier is easy to lose when a retailer shortens the specification to “50,000-hour battery life.” Fifty thousand hours equals about 5.7 years of continuous clock time, but the conversion does not create a five-year replacement schedule. The source ties its claim to setting 6 and the dot. A circle-dot at another brightness is a different condition, and Holosun does not publish an equivalent figure in this manual.

Battery replacement does not require removing the sight because the CR1620 sits in a side tray. The manual directs the user to install the coin cell with its positive side facing down, press the tray into the compartment, and tighten the tray screw to 5 inch-pounds. That small number belongs to the battery tray. Keep it separate from the sight’s mounting torque.

The seal ring deserves more attention than the headline battery figure. Holosun warns that loss or damage to this ring may allow water into the battery compartment and damage the product. If the compartment does not close securely, stop using the optic, remove the battery, and keep the coin cell away from children. A CR1620 requires coin-battery handling precautions.

What can be damaged by the wrong adjustment or torque?

Reticle selection should never involve a screw. The “−” button changes shape on MRS models; the rear elevation turret and right-side windage turret move the zero. Holosun gives the adjustment system a total travel range of ±30 MOA and warns users to stop if a turret binds at its mechanical limit. Forcing it farther may damage the sight.

The same restraint applies below the optic. Holosun’s installation instructions specify 15 inch-pounds for the sight screws, used with medium, non-permanent blue threadlocker. The unit is inch-pounds, not foot-pounds. Applying 15 foot-pounds would multiply the specified torque by 12. Do not improvise that conversion, and do not substitute the battery tray’s 5 inch-pound value for the mounting value.

Mounting instructions also depend on the interface beneath the sight. Holosun tells owners to use a compatible slide cut or adapter plate, select included screws or screws supplied with the slide or gunsmith, and verify clearances and firearm function before use. A plate manufacturer’s directions still govern its own plate-to-slide hardware. If those directions conflict or the screw length is uncertain, an armorer or gunsmith can resolve the actual stack rather than guessing from a forum post.

There are four damage paths the manual identifies or prevents directly:

• forcing a windage or elevation turret after it binds;
• losing, pinching, or damaging the battery-tray seal ring;
• dismantling the sealed housing, which voids Holosun’s warranty;
• using installation torque or hardware without checking the compatible slide or plate instructions.

Changing the displayed reticle belongs nowhere on that list. When the correct MRS command fails, preserve the zero, mount, seals, and housing while the fault is diagnosed.

What is different between the Holosun EPS and EPS Carry?

The EPS Carry is the narrower version intended for subcompact and slim-profile pistols. Holosun’s current specifications give it a 0.77 × 0.58-inch window, 1.63 × 1.07 × 0.95-inch body, and 1.23-ounce weight. The larger EPS uses a 0.90 × 0.63-inch window, measures 1.63 × 1.19 × 0.99 inches, and weighs 1.4 ounces.

Both current families use Holosun’s K footprint and are offered as MRS, fixed 2 MOA, and fixed 6 MOA variants. Their included adapter plates differ. Holosun lists an RMSc-to-K plate with the EPS Carry and an RMR-to-K plate with the EPS. “Carry” therefore describes the smaller housing and adapter context; it does not identify a different reticle-switching command.

An `EPS-RD-MRS` and an `EPS-CARRY-RD-MRS` both use the three-second minus hold and both offer a 2 MOA dot with a 32 MOA circle. An `EPS-CARRY-RD-2` remains fixed at 2 MOA even though its larger-family cousin also exists. Size and reticle package are separate fields in the model name.

Frequently asked questions

Does the EPS Carry have multiple reticles?

Some versions do. Holosun EPS Carry models ending in MRS offer a 2 MOA dot, a 32 MOA circle, and the combined circle-dot. Models ending in -2 have one 2 MOA dot; models ending in -6 have one 6 MOA dot. Check the complete model designation before trying to cycle it.

How do I adjust EPS Carry?

Use brief presses on “+” or “−” for brightness. On an MRS model, hold “−” for three seconds to change reticle shape. Windage and elevation use the mechanical turrets and affect zero, so leave them alone when changing display settings. Holosun warns against forcing a turret that has reached its limit.

What optic cut is the EPS Carry?

Holosun specifies the EPS Carry as a direct-mount K-footprint optic and includes an RMSc-to-K adapter plate. Fit still depends on the pistol’s slide cut, plate, screw thread, and screw length. Verify the host or plate maker’s instructions rather than treating “RMSc compatible” as proof of a universal direct fit.

What is the difference between EPS and EPS Carry?

The EPS Carry is narrower and lighter: Holosun lists a 0.77 × 0.58-inch window and 1.23-ounce weight, versus 0.90 × 0.63 inches and 1.4 ounces for the EPS. Both use the K footprint, but the Carry includes an RMSc-to-K plate while the EPS includes an RMR-to-K plate.

What are the EPS Carry reticle options?

EPS Carry MRS models cycle among a 2 MOA dot inside a 32 MOA circle, the dot alone, and the circle alone. Separate fixed-reticle models provide either a 2 MOA or 6 MOA dot. Current Holosun listings offer red, green, and gold emitters, with color fixed by the purchased model.

How do I use EPS Carry Shake Awake settings?

Hold “+” for 10 seconds, then tap either button to choose the sleep delay. One, two, three, or four LED blinks mean 10 minutes, 1 hour, 12 hours, or OFF. Press both buttons together to save and power down. OFF disables sleep; the factory default is 10 minutes.
