Overview
The L3Harris ATPIAL-C Advanced Laser System is a versatile aiming device designed for tactical applications. It features three operational modes: a red laser for visible targeting, an IR illuminator for low-light scenarios, and an IR laser for use with night vision equipment, all powered by a CR123A 3V lithium battery. This system is commonly found in builds using a mid-length gas system chambered in 5.56 NATO, making it a popular choice for those focused on precision and versatility in various lighting conditions.

L3Harris ATPIAL-C is the duty grade laser system that performs above its price tier compared to less capable alternatives. Visible green and IR lasers plus IR illuminator. Zero retention is solid. Worth it for night vision capable builds.
