Another ACOG/MRD Mounting option
Another trend that’s developed over the years is to mount a mini-red dot (MRD) on top of the 4X Trijicon ACOG series scopes to provide close-range capability and speed that can be difficult with the magnified optic. Years ago, KAC came up with a mount that replaced the rear ghost ring on the TA01NSN ACOG, then in 2003, Specwargear came out with their own Doctor optic/Optima mounts (the SWG Optima mount is shown below). This was followed by JP and others. The drawback to this mounting position is that it’s so high off the boreline that you don’t get any cheek weld. At best, it’s a chin weld. Since it’s for close-range use, the MRD is usually sighted in at 25 yds, where the large offset presents additional problems and needs to be considered when taking shots at distances in that range if precision is needed.
