Don't know too much about USAC, but to the best of my knowledge, it was the only name the company ever went by. Their line of bows was named after different states. You don't see too many of them, but as I recal, they were decent bows for the money, decent shooters, but not nearly as populars as the Bears, Pearsons, Howatts, etc. They weremore in line with th Stottler, Stemmler, and such bows. Just a little lesser bows than say say Shakespeare. Best I can offer , and to the best of my knowledge. Someone with better knowledge might dispute my opinion and I will defer to them.
