I would say most aftermarket drop in stocks on std barrels would end up freefloated,magnum contour probally not,most heavy barrels i think would mostly be freefloated,a factory stock most likely not except for heavy barreled guns.If you want your stock freefloated you can sand the barrel channel to open it up a little if you want it not freefloated you can fully bed it so with a little work most stocks can be made to go either way.
