Not sure if I already posted this, but...
ATN Thor OPMOD 4X/8X thermal scope. Very reasonable price; very solid thermal scope. Did a 50/200 zero, and POI is well within the capabilities of the ammo (TAP 75 SBR / 69 SMK) and the shooter.
I have NVG's as well (PVS-7), but the thermal scope let's me see you whether you are moving or not. Nice edge to have after dark.
Oh...sold my Aimpoint PRO and got another Aimpoint Comp M4S. Like the AA battery and battery life, and I have rechargeable AA's, so now my primary and backup HD uppers have M4S's, and I don't have to stock batteries for them.
Simple, effective, and reliable options.
