The X4-LRF-15K™ includes Maztech’s reliable, low-noise, high-gain APD photoreceiver that offers best-in-class sensitivity, allowing for long-standoff range performance with less laser pulse energy and lower power. To allow optimal APD bias at all operating temperatures, the X4-LRF-15K™ includes automatic APD bias temperature compensation that is calibrated at the factory.

The X4-LRF-15K™ includes co-aligned visible and IR pointers for weapon zeroing and target pointing. Programmable pointer power levels allow the user to optimize for mission-specific parameters. Hotshoe attachment provided for optional IR illuminator and/or future products.


An onboard ballistic computer generates a firing solution and a companion app enables easy configuration control. A keypad is included to enhance usability, enable customization, and facilitate operation from various shooting positions. 

 The X4-LRF-15K™ is developed by Maztech Industries, whose leadership and design team have delivered cutting-edge equipment to the U.S. Military for over 30 years.
