Trijicon's famed ACOG series now comes in a version that takes a single AA battery - with a run time up to 12,000 hours. With two calibers (5.56 NATO/.223 Rem. and .308 Win./7.62 NATO) and three reticle styles (chevron, horseshoe and crosshair), there's a battery-powered ACOG to suit most needs.
MSRP: $1,548.
