One word...WOW. The new TAC 15 and TAC 15i (no AR lower needed) are both top of the line bows. The triggers are just amazing, very much like a fine rifle trigger. PSE has chosen a rail less design, and it is working. I was literally shooting nocks off with ease. Everything was quality throughout. The only negative I seen was the length, at 47 1/2 inches long they are not for everyone. Very quiet and no vibration. The rest of the line has remained nearly the same.
