Some float the back end of the stock but on mine it has solid contact with the receiver and hanger the barrel is free floated. It shoots great so I won't touch a thing.
Thats goid bevause it the barrel is not touching the forend then floating the back of the forend would not do a thing except make an ugly gap...
The whole idea (or more correctly- theory) is that if the forend is bedded to the barrel, the barrel heat MAY cause enough expansion to move the forend back enough to bind the forend bewteen the action and the barrel so that harmonics /accuracy is affected.
The rear of the forend would have to be pretty tightly bedded to the receiver to cause that and the Brownings just have a flat butt joint between the two. The Ruger number 1 & 3 rifles have that angled forend screw which pulls it up and back toward the action. That is what can cause the fit issue if the barrel is not floated.
