Before i would even think of the options you are talkling about i would shoot you gun,like 200-300 rounds then see how it does.There are MANY factors to increase accuracy.With a new gun you have to settle the barrel in and the barrel needs rounds throught it to take out some of the stress when being made and settle it down. Free floating stock put out by some manufactors is done basically to cut down production cost. Free flaotating started years ago with some target shooters. These options are when nothing else works in accuracy. do what i said first then go down that trail.Hope this info has helped. vangunsmith
