How does this prism work? ~ TACOM HQ Charlie Tarac ~ Rex Reviews

​TACOMHQ was founded by John and Jacob Baker (father and son). John used his optical engineering degree and thirty (30) years manufacturing as project and technical director and ISO-TS quality system experience to establish a new product category for optics. John and Jacob developed a series of products that are radically changing the way the industry looks at a rifle and its support components with simple, yet ingenious ideas. ​Having already shattered two long standing world records in less than a year for longest confirmed sniper kill and world’s longest shot measuring an incredible 5,000 yards or miles made with the Charlie TARAC by retired US Navy Seal sniper Charlie Melton at Charlie Mike Precision, TACOMHQ and its products command results. Their supporters include Accuracy 1st, Applied Ballistics, Brad Stair, Bryan Litz, Charlie Melton, David Tubb, Derek Rodgers, Eduardo Fontcuberta, Frank Galli, “Mad Max“ Mullen, McMillan, Mark and Sam after Work, Mitchel
