I have MkII GL, the left handed plain-jane version of the MkII with a standard configuration "hardwood" stock and it shoots reasonably well.

However, I was wondering if it's worth sanding out the barrel channel to free float the barrel. Currently, I can't slip a piece of paper through the channel with the barreled action installed so the barrel is touching the stock at several places and this can't be doing the accuracy any good. Has anyone done this and did it help?
