Bush said that he supported the AWB. In 2000, when running for president.
As president, he kept it in place. He had plenty of time and dealt with far smaller issues. After 911, when security was a worry, it would have been the PERFECT time to nullify the bill. Nope. he left the bill in place, just as he promised in 2000.
So yes, bush was an anti-gun mfer. let's just see ya disprove that one, champ.
