RE: Beddding the lug......
I have glassed in several guns including semi-autos. First is there a problem with it's accuracy? Second is the stock wood or synthetic? I asume it's wood. If you want to you can bed the action and free float the barrel at the same time sealing the inside if the barrel channel with glass-bedding so it will not draw moisture and warp. Thats the standard full treatment for a bolt-action sporter. If it needs it. But if its a shooter I'd leave it alone. At the least you may want to apply a THIN coat of epoxy to seal any exposed wood on the inside of the stock.
