L3Harris ATPIAL-C laser system has held zero through multiple range sessions and removals. Three positions for visible green, IR laser, and IR illuminator. Switch is on the body with intuitive layout. Worth the premium price for a duty grade laser.
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.
