In 2009, the following enhancements will be available to select Trijicon ACOGs: Green reticles will be availble in ACOG models, as well as red and amber. Green allows the Human eye to adjust to it very quickly, and appears very bright in low to no light situations; horseshoe reticle patterns, developed at the request of the U.S. Military, will be available on the ACOG calibrated for the 6.8 SPC round, allowing for the conversion of an AR15 into an ideal hunting rifle.
