I agree. My 700 varmint 223 I just got was not free floated, but having shot it, I don't think it needs it. Getting groups less than an inch mostly. My friend did free float his 700 ADL heavy barrel 223 but it did not seem to improve it. However, it was shooting very good before anyway. This guy just likes to bed guns.
Go burn some powder.
Best of luck,
