Are you by chance right eye dominant? Just curious, it seems common for lefties.
The G2 is good bang for the buck.
I use a scout on my helmet, a Pentagon IR Flood up there as well,
Turbo head 12V on my short gun, I use P pads instead of push button.
My secondary light was a Gladius but it broke three times from getting shot by SIM in the killhouse so I dumped it for another Surefire, cant recall its nomenclature.
I use Aimpoint and EOTech dependant on which upper Im using.
I like the LMT fixed rear, I never put the irons down so I just go with the fixed.
For rails Ive been using LaRue for a couple years. Unless I need lasers I go with regular guard rails with a fabricated mount for my light.
