I have a Jetbeam RRT-2 Raptor, which is an awesome torch, slightly brigter than the Eagletac P20C2 mk III. I am yet to mount it to my rifle but I have no doubt that it will perform brilliantly.
My brother in law has a wolfeyes sniper 260 which is marginally brighter than the jetbeam but nearly double the cost.
Cheers Bushy
