Works great, only wish they didn't go with different design for tail-cap and mounting screw/bracket. - Streamlight TLR-VIR II Weapon Flashlight and IR Laser

I see a lot of people calling the IR illumination too dim or only good for close range, I think this may depend on what type of NVD you have.

I have a SiOnyx Aurora Pro, and it picks up the IR illumination pretty good, 25 yards if not a bit more... Switching modes is very easy as well, the '300 lumen' white light is bright for what it is. The IR laser itself shines bright well past 100 yards. So for most people wanting something that will work with NVDs to see/shoot at ranges out to maybe 100 yards or even a bit further, this will work great... Unless perhaps your NVD doesn't pick up the illumination as well, I can't speak for everyone in this regard. But the Aurora Pro seems to pick up a wide variety of IR illumination devices quite well...

Cons: The tail cap is not standard TLR, so you have less interchangeability with older/other systems... Also the mounting screw/bracket, is different, they are both smaller. The bolt is a smaller diameter, so don't be like me and buy a larger 'rifle kit' screw for this then find out it's not the right size/threads...

Overall I'm keeping it on one of my short AR pistols, its right at home on it.
