I am a new Garand owner (CAI receiver, PB barrel, WRA trigger, SA bolt, walnut BMR stock, birch guards) and have ordered a new American Black Walnut stock set to "dress up" my Garand. Removing buttstock is simple, but the guards appear to be more complicated. I have ordered clip pliers for the rear guard. It's the front guard I'm not sure about. Do I have to remove the front sight, gas cyl lock screw & lock (ordered a lock wrench), and remove the gas cylinder from the barrel in order to get the old front guard off, or do I merely need to loosen the cyl enough to push it forward and pull the guard off from the top? If I have to remove the gas cyl, do I have to remove the op rod from the rear of the gas cyl before I remove the cyl itself? Any assistance would be sincerely appreciated.
