The AN/PEQ-2A is a Class 3b lightweight, self-contained, battery-powered infrared (IR) laser aiming light/ illuminator. When zeroed to the weapon and activated, the AN/PEQ-2A projects an IR dot that illuminates on the target and is visible only with image intensifying night vision devices. The Rail Grabber Mounting Bracket allows the Aiming Light to be attached to all weapon mounting rails as defined in the MIL-STD-1913. This device replaced the AN/PAC-4C. Capability will be replaced by AN/PEQ-15 & 16A in the Ground Combat Element.

The AN/PEQ-2A attaches to the upper receiver of the M16A4/M4/M249 and M240. The Bracket Adapter is compatible with the TPIAL and the mounting brackets used on the M2 and M19 Heavy Machine Guns.

This item is being replaced by the AN/PEQ-15 ATPIAL
