Trijicon 4x32 BAC ACOG Rifle ScopeDual Illuminated Green Crosshair 300BLK Reticle w/TA51 Mount. The 300 blackout reticle with merged aiming points has been optimized for simplicity and efficiency. It allows the user to instantly switch between supersonic and subsonic ammunition without having to re-zero the optic. The supersonic BDC (out to 600 yds.) has been merged with the subsonic BDC (out to 200 yds.) to provide one set of aiming points for both types of ammunition. The reticle drops are based on an average of commonly available off-the-shelf subsonic and supersonic ammunition from a 16" barrel. This BDC reticle is not limited to one or two specific bullets: a majority of commonly available ammunition will fall within the 2 MOA diamond aiming points. The 2 MOA diamonds offer a balance of speed and versatility based on the unique performance of the 300 Blackout caliber. The drops in MOA for each aiming point are provided for users who wish to develop their own handloads for use on firearms with a barrel of 16" or shorter or for those who wish to deviate from the recommended zero distances.
