Description
Precision aiming at your fingertips with military-grade durability in a lightweight, weather-ready package designed for serious rifle setups.
Quick target acquisition shouldn’t require sacrificing rail space or breaking the bank. The Holosun LS117R delivers professional-grade laser performance in a compact form factor that mounts securely to any 1913 Picatinny rail and removes just as quickly when not needed. Its 5mW visible red laser provides daylight visibility up to 100 yards, while the included remote pressure switch allows instant activation without shifting your grip. Built from aerospace-grade 7075-T6 aluminum with IP67 waterproofing, this laser sight handles demanding environments while running up to 5,000 hours on a single AA battery.
Key Features
- Quick-Detach Picatinny Mount: Tool-free attachment and removal with secure lever-lock system ensures zero retention through repeated mounting cycles
- Dual Brightness Settings: Toggle between 1mW low-power mode for close quarters and 5mW high-power mode for maximum daylight visibility out to 100 yards
- Extended Battery Life: Single AA battery provides up to 5,000 hours of continuous operation, with convenient battery access for quick field changes
- Precision Adjustments: Tool-free windage and elevation adjustments with 0.5 MOA per click and ±50 MOA travel range allow fast zeroing without extra equipment
Important Compatibility Notes
- Requires 1913 Picatinny rail (standard MIL-STD-1913 specification)
- Designed for long gun applications, including AR-15, AR-10, and similar tactical rifles
- Remote pressure switch cable measures approximately 45 inches for flexible placement options
- Protective rubber cover included to shield laser emitter during storage and transport
Why We Carry It
The LS117R represents Holosun’s commitment to bringing professional-grade features to shooters at accessible price points. Since launching in 2013, Holosun has earned recognition from law enforcement and military users for producing optics and lasers that perform reliably under hard use. The 635nm red wavelength on this model provides better visibility than standard 650nm red lasers found on budget options, while the aircraft-grade aluminum construction ensures the zero holds even under heavy recoil. Users consistently report that the included hard case with molded foam insert is actually worth using for storage, unlike throwaway packaging from many competitors.
Frequently Asked Questions
Will this laser be visible in daylight conditions?
Yes, the 5mW high-power setting provides daylight visibility at practical distances up to approximately 100 yards. Red lasers perform best in low-light and indoor conditions, though visibility decreases in bright sunlight compared to green lasers. For optimal daytime performance, zero the laser at 25 yards and confirm your zero on paper targets.
How do I activate the laser with the remote pressure switch?
The rear selector switch offers three positions: OFF, constant ON, and REMOTE. When set to REMOTE mode, the laser activates only when pressing the included pressure switch, allowing momentary activation. In constant ON mode, the rear button toggles the laser regardless of the pressure switch input. Most users mount the pressure switch within reach of their support hand thumb for rapid activation.
Is this laser suitable for home defense applications?
The LS117R works well for defensive rifle setups, particularly in low-light scenarios where red lasers excel. The IP67 waterproof rating means it handles humidity and condensation without issue, while the 7075-T6 aluminum housing withstands 1,000G vibration testing. The 5,000-hour battery life ensures the laser remains ready even with infrequent use, though replacing the battery before critical training or defensive deployment is recommended.
