Hand guard free floated.
Floating the HG is a little more work and you have to be very careful not to over do the material removal.. The beauty of the free floater is the HG can be removed without digging out old epoxy, there are other good things also.
The concept is to have the HG mounted in such a manner that it seeks it's own sweet spot, under no pressure or offering any pressure to anything else..
The Front band tabs need to be bent up to ensure no contact occures between the FB and the stock ferrule, at the top. This is not the same clearance as the gap between the front of the stock band and the ferrule, that has to be there also..
To float the HG material has to removed from the HG tenon to a point the tenon slides into the FB without pressure, a slip fit.. Remove material from the back end of the HG so when it is fully seated against the Fb there is a gap of at lease 1/16 inch between the end of the HG and the face of the reciever..
Next, the HG retaining clip tabs have to be ground off to a point where the tabs just slip into the slots on the barrel, the tabs have to be secpure, but just. Round the eges of the clip tabs so the Hg can, by hand, moved back and forth freely under recoil.
Assemble the modified HG and you are finished. When you fire the HG will come to rest just where it likes, leave it alone.
The Service Teams epoxy the HG in place, a good idea,, these Service Match M14's did not always get the loving touch given by M1A owners today.
