Holosun LS117IR Tactical NVG-Optimized IR Laser Module Picatinny
Holosun LS117-IR — Compact Infrared Laser Aiming Device in 7075 Aluminum
The Holosun LS117-IR is a compact, single-beam infrared laser aiming device operating at 800–880 nm in a lightweight 7075-T6 aluminum housing. It is designed for use with night vision devices on rifles, carbines, PDWs, and submachine guns. The LS117-IR is the entry point of the Holosun laser lineup relative to the titanium-bodied LE series — offering the same IR aiming capability at a lower weight and price point, powered by a universally available AA battery instead of CR123A.
The beam is invisible to the naked eye, producing a clearly defined aiming dot visible through Gen 1, Gen 2, Gen 3, and digital NV monoculars and binoculars.
Housing and Construction
Machined from 7075-T6 aluminum with a matte black anodized finish. Weight is 138–145 g with dimensions of 76–88 × 38–46 × 33–36 mm depending on variant. Rated IP67 for water resistance (submersion to 1 m for 30 minutes) and validated to 1000 G vibration resistance. Working temperature range is −40°C to +51°C, storage to +65°C.
Powered by a single AA (LR6) battery — globally available in any convenience store or supermarket, eliminating specialized battery logistics in the field. Battery life reaches up to 5,000 hours. The QD mounting system is integrated directly into the housing base, fitting Picatinny and Weaver rails without additional adapters.
Infrared Laser System
IR Laser (800–880 nm, Class 2M):
- LOW: 0.1 mW — high-sensitivity NV devices and confined reflective spaces
- HIGH: 0.7 mW — standard field mode for Gen 1 / Gen 2 / Gen 3 and digital NV
The collimated beam produces a tight, defined dot without visible spread at practical engagement distances. Class 2M under IEC classification permits higher instantaneous power during scanning while remaining in a relatively permissive regulatory tier in most EU member states.

Controls and Activation
The rear rotary selector has three positions:
- OFF — unit off
- ON (Constant) — continuous laser operation
- REMOTE — activation via cable switch only
The enlarged lever switches reliably with gloves. The included Crane-plug remote cable switch mounts on the fore-end with Velcro or a cable clamp, providing momentary activation — laser fires while pressed, deactivates on release. Windage and elevation adjustments use tactile 0.5 MOA/click turrets within a ±60 MOA travel range, using the included T10L key.
LS117-IR vs LE117-IR
Parameter | LS117-IR | LE117-IR |
Housing | 7075-T6 Aluminum | Grade 5 Titanium |
Weight | 138–145 g | 190 g |
Battery | AA | CR123A |
Battery Life | 5,000 hours | 5,000 hours |
Water Rating | IP67 | IPX8 |
Vibration | 1000 G | 1000 G |
Price Tier | Lower | Higher |
The LS117-IR is the preferred choice when minimum weight and maximum battery accessibility are the priority, and the premium titanium construction of the LE117-IR is not required.
Field Applications
PDW and compact carbines. The small footprint leaves room for a light and grip on short fore-ends. On platforms like MP5, Scorpion EVO, or B&T APC, the LS117-IR adds IR aiming capability without adding meaningful bulk.
Nocturnal hunting. AA availability eliminates specialized battery sourcing. 5,000 hours of battery life covers multiple hunting seasons under typical intermittent use.
NV training. LOW mode (0.1 mW) reduces IR signature in enclosed training facilities with reflective surfaces. HIGH mode (0.7 mW) produces a visible dot through Gen 2 and digital NV at 50–100+ m.
