Surplus L3 Harris Green Laser Interdiction System (LA-12). These were commonly seen in use on M4A1 carbines under the early GWOT.
The Green Laser Interdiction System (GLIS) is a rifle-mounted laser that allows the Soldier to interdict hostile actions through non-lethal effects. It can divert, disrupt or delay potential threats before they can engage friendly forces. It is also an effective, non-lethal means to warn civilians they are approaching a zone of military operations.
Guys don't overlook this... it's a fantastic item to add to your collection. I highly recommend.
