Shake Awake ensures the sight is always ready, powering down when idle and activating with movement.Mounting is straightforward with the QD system, and the optic holds zero even after battery changes or removal. Twelve brightness levels, including two for night vision, allow fine-tuning for any lighting. Windage and elevation adjustments are made in 0.5 MOA steps using the included tool.Practical ConsiderationsThe included QD mount allows for rapid attachment and removal on Picatinny rails.Flip-up lens caps and the kill flash can be rotated or removed as needed.The optic is suitable for both absolute and lower 1/3 co-witness setups, with mounts included for each.Maintenance is minimal: clean the lens with a soft cloth and keep the caps closed when not in use.Holosun HE515CT-RD is available at a competitive price in our selection of tactical optics.

Holosun ELITE HE503CU-GR — built to survive the field and shave seconds off splitsIf gear gets used hard—wet dawn hunts, muddy barricades, vehicle classes—the HE503CU-GR stays on target when cheap dots fade. The green reticle is crisp against brush and dark hides, the housing shrugs off knocks, and the hybrid power system keeps the sight alive when a coin battery would’ve died at the worst time. It’s the compact optic that doesn’t ask for babysitting. Ready to buy today or place a quick order across Europe through Professional Optics at a competitive price.What you actually feel on the rifleGreen MRS reticle is fast without being splashy. Run the 65 MOA circle for snap shots in thickets or tight CQB—then drop to the 2 MOA dot for a precise hold on small vitals. No hunting for the dot, no bloom in bright noon sun. Easy to buy as a complete package with mounts included.Solar + CR2032 means real uptime. Leave the rifle staged, throw it in the truck, or drag it through a weekend match—the sight wakes, runs, and doesn’t nag. Shake-awake does its job; manual control is there when needed. Order with confidence for reliable duty use.Controls that don’t fight gloves. Positive clicks, 0.5 MOA adjustments that track, daylight-bright levels plus two for NV if night devices are in the kit.Mounting that just works. Low or lower 1/3 co‑witness out of the box—AR carbines, shotguns, PCC, or a stout airsoft replica—no parts hunt required.Technical specifications Holosun ELITE HE503CU-GRParameterDetailReticle2 MOA green dot / 65 MOA circle‑dot (MRS)Illumination levels10 daylight + 2 night‑vision compatiblePower systemSolar Failsafe + CR2032 batteryStated battery lifeUp to 50,000 hours (dot-only, medium setting)Motion activationShake Awake (sleep/wake with movement)Click value0.5 MOA per clickElevation/Windage range±50 MOA totalWindow diameter20 mmHousingTitanium alloy body, black finishWaterproof ratingIP67Mounts includedLow mount + lower 1/3 co‑witness mountDimensionsApprox. 67 × 60 × 37 mmWeight~96 g with mountField use scenarios that match this opticDriven boar or predator at dusk: circle‑dot locks faster on moving shapes in tangled backgrounds; the green stays visible when red starts to wash.Shotgun or PCC on steel: center with the circle, press; recoil won’t lose the dot and the window gives enough context to stay aggressive.Patrol carbine / training days: leave it in the rack; solar backup and sleep/wake keep the reticle there when the door opens.Airsoft Milsim in rain and dust: sealed body, sensible controls, won’t flicker under impacts or when weather turns.Installation, zero, upkeep — minimal fussMount: choose the included low or lower 1/3 base, apply thread locker (blue), torque per spec (tight but not heroic), verify rail tension.Zero: start at 25 m to get on paper, confirm at 50 m for a clean defensive/hunting zero; 0.5 MOA clicks make fine correction predictable.Maintenance: wipe the lens with a blower and lens pen; inspect cap O‑ring; swap CR2032 once a season if mission‑critical, even though the runtime is long.Why this model earns its space in the safeReliability from power redundancy and sealed construction.Real speed from a clean green MRS reticle that presents fast and scales to precision.Durable housing and mounts that hold zero under recoil and travel.Practical ownership: easy setup, rare battery swaps, no drama in bad weather.
