yes I have installed it on my Tac. Took me a long time to get it tuned. Dorge has made a mod as the balls on the fingers would stick and you would get major flyers if you did not reset it by pushing the balls down with your fingers. That took me a while to suss out why my groupings were so bad. As for more speed I do not know but it is one increadible peice of engineering. So simple yet so smart. All I need is for Dorge to design a broadhead for his Aerobolt 200 and his Aerovane III and I will search no more. Cut on contact if that is possible like the Helix. I love that broadhead but just cannot get good results.
