Infrared super tac 850nm - Streamlight Tactical Super Tac C4 LED Flashlight

This is the second Super Tac 850 NM infrared LED light I have purchased. When coupled with a Yukon Gen 1 NV scope it is AMAZING how much IR light this thing puts out. On my "night hunter" AR-15 I can easily shoot for groups at 100 yards, even on the darkest of nights. A great item to have to boost any Gen 1 NV setup. The only reason I dinged it 1 star on "useability" is because it would be double awesome if you could switch out the head assembly with an ambient light C4 LED head for use as a regular flashlight... Replacement heads are not available, however.
Pros: Light, Bright!, tough...
Cons: Wish could replace heads with standard C4 LED
