Holosun Ronin-AEMS-Max-GR Max Green MRS Sight 2 MOA dot, 65 MOA circle Solar Failsafe + Shake Awake
Holosun Ronin AEMS-MAX-GR — Enclosed Reflex Sight with Green MRS Reticle and Maximum Field of View
The Holosun Ronin AEMS-MAX-GR is an enclosed reflex sight featuring the largest optical window in the Holosun lineup: 40×30 mm (1.57″×1.18″). Compared to the standard AEMS, the lens area is approximately doubled, delivering a substantially wider field of view while maintaining the sealed, compact enclosed form factor. The sight carries a green 540 nm LED, a three-mode MRS reticle system, triple-source power (battery + solar panel + supercapacitor), and the Ronin Dragon engraving that identifies the Ronin Special Edition series.
The AEMS-MAX-GR is built for shooters who prioritize rapid target acquisition, both-eyes-open shooting, and magnifier compatibility on rifles, carbines, and tactical long guns.
Housing and Construction
Machined from 7075-T6 aluminum with a matte black anodized finish. Weight with mount is 295 g (10.4 oz), housing dimensions are 49×64 mm (1.94″×2.51″). Glass flip-down lens covers for both front and rear lenses are included. Rated IPX8 for full water submersion and validated to 1000 G shock resistance. Working temperature range is −30°C to +60°C, storage −40°C to +65°C. The side-mounted CR2032 battery tray allows battery replacement without removing the sight from the rail.
Optics and MRS Reticle System
Multi-layer coated lenses deliver a clear, contrast-rich image with zero parallax at all practical distances. Magnification is 1× with unlimited eye relief. The 40×30 mm window area is approximately twice that of standard 20 mm micro-format sights and provides a field of view approaching that of full-size tube optics.
Multi-Reticle System (MRS) — three selectable modes via dedicated button:
- 2 MOA dot — precision aiming at medium and extended distances
- 65 MOA Circle — rapid target capture for close-quarters engagement
- Circle-Dot — combined 2 MOA dot inside 65 MOA ring for universal application
Reticle color: green, 540 nm wavelength — the peak of human photopic sensitivity, making the green dot faster to acquire visually, particularly under mixed and overcast lighting conditions.
Triple Power System: Solar Failsafe + SuperCap + CR2032
The RONIN AEMS-MAX-GR runs on three independent energy sources:
- CR2032 battery (3V) — up to 50,000 hours of runtime at level 6 in dot mode
- Solar Failsafe panel — automatically adjusts LED intensity to ambient light; under sufficient illumination the sight draws no battery power
- Supercapacitor — internal energy buffer that provides approximately 200 hours of autonomous operation in dot mode at level 6 with a depleted battery and no light source
The 50,000-hour CR2032 battery life represents over five years of continuous operation from a single battery costing under €1.

Shake Awake and Brightness Control
Shake Awake powers down the LED after 10 minutes of inactivity and reactivates the sight instantly on the first movement of the firearm. The last-set brightness level is stored in memory on wake. Two side-mounted buttons control brightness with a 3-second hold engaging Solar Auto-Brightness mode, where the sight continuously adjusts the LED intensity to match ambient conditions — practical for transitions between indoor and outdoor environments.
Magnifier Compatibility and Mounting
The enclosed housing and Lower 1/3 Co-Witness mount at 41.4 mm bore height align correctly with standard magnifier devices (Holosun HM3X, Vortex Micro 3×, Sig Sauer JULIET3) on AR-platform rifles. The co-witness height allows the AEMS-MAX-GR to be used over folded-down BUIS. The wide AEMS footprint directly accepts other AEMS-footprint optics without adapters.
Field Applications
Hunting. Green 540 nm provides superior contrast over foliage and vegetation backgrounds compared to red, making the dot easier to pick up when animals emerge from treelines or brush. Circle-Dot mode for fast acquisition; 2 MOA dot for precision shot placement. Solar Failsafe eliminates battery depletion risk during multi-day expeditions.
Airsoft and tactical sport. The sealed housing protects the optical surfaces from BB strikes. The 40×30 mm window maintains maximum situational awareness during dynamic sector changes and room-to-room transitions.
Carbines and rifles. The wide FOV combined with 65 MOA Circle mode delivers target acquisition speed comparable to holographic sights at significantly lower cost and weight. Magnifier compatibility extends the sight's effective range without a dedicated LPVO.
