How To Change EPS Carry Reticle: Complete Holosun Programming Guide
Changing the reticle on your Holosun EPS Carry open reflex sight requires a precise two-button programming sequence using the down adjustment arrow to cycle through the 2 MOA dot, 32 MOA circle, or combined solar-charged multi-reticle system. Mastering this mode allows you to optimize your pistol-mounted optic for rapid target acquisition in high-stress defensive scenarios or precision target shooting.
Pre-Operation & Equipment Checklist
Executing a reticle change on an enclosed micro pistol optic like the Holosun EPS Carry requires understanding the physical button layout, battery state, and environmental considerations. Because these micro optics are engineered for sub-compact and compact handguns with tight slide tolerances, ensuring unobstructed access to the optic housing prevents accidental setting modifications or housing damage.
- Essential gear, tools, and materials: Holosun EPS Carry optic (mounted or unmounted), the multi-tool or T10 Torx wrench included with your factory packaging, a clean micro-fiber cloth, and a fresh CR1632 3V lithium coin cell battery if power delivery is degraded.
- Mandatory prerequisite knowledge and standards: Familiarity with the side-mounted battery tray, waterproof gasket seating, and the operational distinction between the illumination intensity buttons (marked plus and minus) and the programmable reticle cycling function.
- Estimated budget and duration benchmarks: Zero financial cost and an execution duration of under sixty seconds, provided the optic firmware and battery retain adequate voltage above the low-voltage flashing warning threshold.
Step-by-Step EPS Carry Programming Workflow
Step 1: Verify Optic Power and Battery Health
Before attempting to modify the internal reticle projection profile, confirm that the EPS Carry is powered on and operating above the low-battery voltage threshold. If the LED emitter exhibits a slow, randomized flashing pattern upon wake-up, the CR1632 lithium cell must be replaced using the side-mounted tray secured by T10 Torx screws before attempting any programming sequences.
Warning: Never over-torque the T10 screws on the EPS Carry side battery tray during maintenance, as stripping the aluminum housing threads compromises the IPX8 waterproof rating and voids the manufacturer warranty.
Step 2: Locate the Multi-Reticle System (MRS) Control Button
Examine the left side of the EPS Carry aluminum housing to locate the two adjustment buttons. The upper button is traditionally designated as the plus arrow for increasing brightness intensity, while the lower button is designated as the minus arrow for decreasing brightness and controlling the multi-reticle configuration.
Step 3: Execute the Reticle Cycling Command
Press and hold the minus button (down arrow) continuously for approximately three to five seconds without releasing pressure. Watch the projected reticle inside the aspherical glass lens window until the pattern blinks or cycles to the alternative configuration, indicating that the emitter has successfully registered the command and switched memory states.
Step 4: Cycle Through Available Options
Release the minus button immediately after the reticle changes, then repeat the short press-and-hold sequence to cycle through the three factory-programmed reticle options: the standalone 2 MOA precision aiming dot, the sprawling 32 MOA outer ring for rapid close-quarters acquisition, or the combined dual-pattern reticle featuring both the ring and the center dot.
Pro-Tip: If your EPS Carry model features solar failsafe technology, ensure the ambient light sensor on top of the hood is unobstructed during programming to prevent automatic brightness modulation from interfering with visual confirmation of the new reticle style.
Step 5: Save and Lock the Selected Reticle Profile
Once your preferred reticle configuration is projected clearly onto the coated glass, cease all button inputs for three seconds. The Holosun internal memory will automatically lock and save the chosen pattern, ensuring that subsequent automatic wake-ups via Shake Awake technology or manual power cycles default to your verified setup.

EPS Carry Technical Specifications & Reticle Matrix
| Reticle Configuration | Diameter / Size | Primary Application | Battery Drain Impact |
|---|---|---|---|
| Standalone Dot | 2 MOA Center | Precision grouping and distance shooting | Lowest current draw |
| Outer Ring Only | 32 MOA Circle | Rapid close-quarters instinctual index | Moderate current draw |
| Combined System | 2 MOA Dot & 32 MOA Circle | Versatile tactical and defensive use | Highest current draw |
Common Troubleshooting & Field Fixes
- Symptom: Holding the minus button causes the brightness to dim all the way down without changing the reticle style.
- Root Cause: The button hold duration was either too brief to trigger the secondary circuit or the user pressed the power-up plus button by mistake.
- Actionable Fix: Ensure you press and hold the lower minus button firmly and maintain continuous downward pressure for a full five Mississippi counts until the LED flashes.
- Symptom: The reticle pattern changes successfully, but the illumination is faint or washed out against bright daylight backgrounds.
- Root Cause: The optic is locked in a low manual brightness setting or the solar failsafe sensor is covered by accumulated debris, oil, or holster lint.
- Actionable Fix: Clean the solar panel array with a dry micro-fiber cloth and tap the plus button to step up the manual intensity override levels.
- Symptom: The EPS Carry drops its programmed reticle setting and reverts to the default dot every time the slide cycles under live-fire recoil.
- Root Cause: Voltage sag caused by a failing battery or a loose battery tray failing to maintain constant electrical contact under g-force acceleration.
- Actionable Fix: Swap the CR1632 battery for a fresh industrial-grade cell and ensure the side tray is snugged down completely flush with the housing.
Frequently Asked Questions
Can all versions of the EPS Carry change their reticle?
No, only models explicitly designated as Multi-Reticle System (MRS) variants feature the internal circuitry and dual-emitter setup required to switch between the dot and circle combinations. Standard single-dot models are permanently locked to the standalone 2 MOA or 6 MOA dot projection.
Does changing the reticle affect my zero?
No, switching between the 2 MOA dot and the 32 MOA outer ring utilizes the exact same central point of impact coordinate baseline. Your zero remains completely undisturbed because the center dot position is anchored within the physical emitter architecture.
Why does my EPS Carry reticle flash on and off?
A flashing reticle on a Holosun optic serves as a built-in diagnostic warning indicating that the system voltage has dropped below the operational threshold due to an expiring battery. Replace the CR1632 coin cell immediately to restore standard illumination stability.
Will the optic retain my reticle choice if the battery dies?
Yes, the selected reticle configuration is stored in non-volatile flash memory within the optic's logic board. Once a fresh battery is installed, the EPS Carry will instantly recall and project your custom reticle profile without requiring reprogramming.
