Description
Across bright desert three-gun competition stages the Holosun HS510C HM3X Combo Kit delivers lightning-fast close-quarters speed alongside three-power magnification reach. Bundling an open reflex sight and flip-to-side magnifier in a hard travel case, it yields 50 MOA elevation travel with 1/2 MOA clicks, providing instant two-eyes-open framing and medium-range target identification.
Constructed with an open aluminum housing shielded by a titanium-alloy hood, the reflex sight withstands severe barricade impacts and heavy match cycling. Multi-coated optical glass surfaces optimize photon throughput, ensuring clean image clarity through fog and dim twilight. Sealed O-rings prevent moisture ingress, satisfying IP67 water-resistant standards down to 1 meter. Weighing 19.4 ounces combined across an 8.0-inch total footprint, this combo integrates clean weapon balance, showcasing practical Holosun tactical optic combo engineering.
Key Features of Holosun HS510C HM3X
Competitive carbine shooters buy Holosun HS510C HM3X Combo Kit systems to transition between unmagnified room-clearing speeds and 500-yard steel targets with a flick of the wrist. The included HM3X magnifier flips aside with firm hand pressure.
- 65 MOA circle with 2 MOA red dot provides rapid close-quarters center-mass aiming
- HM3X 3x optical magnifier flips to the side for instantaneous unmagnified shooting
- Solar Failsafe backup powers the reflex reticle through ambient light if battery reserves fail
- 50 MOA total internal elevation stroke accommodates diverse projectile drops on modern carbines
- Quick-detach lever mounts clamp straight to Picatinny rails with repeatable zero return
- Shake Awake motion sensor preserves battery life while ensuring instant deployment readiness
- Tool-free fast-focus diopter on the magnifier sharpens reticle lines for individual eyesight
- Heavy-duty foam-lined hard case protects both optical units during vehicle transport
Combo System Recoil Shock Boundaries
The potted red LED emitter core and fixed magnifier prism withstand 1000G shock loads from sustained rapid fire on centerfire carbines. Adjustment screws on the reflex sight provide 1/2 MOA clicks across 50 MOA travel, locking zero through sustained rapid semi-automatic fire. Operating temperatures span from -22°F to 140°F, preserving lithium battery performance and internal seal integrity. The reflex pattern stays parallax-free across the entire glass window.
Combo Rail Receiver Spacing Clearances
Mounting this combined sighting system requires 4.8 inches of uninterrupted Picatinny rail space on flat-top receivers. High-strength quick-detach levers must be adjusted to clamp snug against rail ribs without play. Eye relief spans 2.75 inches behind the magnifier, providing safe stand-off distance from the ocular bell during rapid shooting strings.
Combo Sight Field Handling Regimen
Side push buttons allow operators to adjust illumination intensity with tactile clicks even with the magnifier deployed. This non-night-vision combo system is not engineered for nighttime operations with night-vision goggles, nor for 1000-yard benchrest matches. Practice structured preventive maintenance to ensure uninterrupted field performance.
- Brush fine dust and dirt from outer lenses using a soft brush every 250 rounds
- Check base mounting clamp levers with an inspection wrench every 500 rounds
- Slide out the reflex battery tray to replace the CR2032 cell every 12 months
