Low Power Variable Optics (LPVO)

In general, I prefer LPVOs with large objective lenses, because they should gather more light and provide clarity in darker situations. I have them for hunting and self-defense, not target shooting.

Burris MTAC 1.5-6x42mm Riflescope w/Ballistic AR reticle
I have one of these on my FightLite SCR.
Nikon M-300 BLK 1.5-6x42mm Illuminated BDC SSD
I really like this optic, but it is discontinued.
I have one of these on my Remington 700 SPS.
Konus Pro M-30 1.5-6x44
I definitely don't love this scope.
I have one of these on my PTR-91.
