I've tried 8 different brands of ammo in my M&P 15 5.56 1:9 twist at 100 yards with a Nikon 3-9x scope. 5 - 10 mph wind right to left. Narrowed it down to these three.
Hornady .223 55 gr. 1.625" group Federal .223 55 gr. 1.75 " group Black Hills .223 68 gr. 1.75 " group Is this the best I should expect or should I be doing better? The gun has about 200 rnds thru it and the trigger still seems a bit rough. |

Free Float in theory should make a rifle more consistent,not necessarily more accurate. Unless one is really winding up a sling tight I don't think its is such a big deal. YMMV
At any rate try (if you can find any) Win " Varmint 45gr 3600fps" . I have found it to be a good shooter in several different 1/9 bushmaster barrels. Before you spend a bunch on a Free Float I would first look at your trigger situation |

All mine have YHM free float tubes on them. I like them. But there are other good brands out there too. Take a look around and see what you like. I really like the YHM customizable forend because it has a very slim profile that feels good in my hands, but also lets me put rails on it where I want them.
Here is a pic of one of mine:
