Hi welcome to the forum and congrads on your new M1icon Rifle. You will enjoy shooting the rifle. I good range test is a must to see how the rifle will perform. I am banking on the rifle not being accurate the way the muzzle completely swallows the cartridge bullet tip in your pics. If the barrel is a goner your definitely want to replace the barrel to get the rifle's full shooting potential. Since a barrel can be a significant investment you may want to consider changing the caliber to 308 Winchester as that cartridge is more readily available. Again its more of a personal choice. I would strongly recommend that you replace all of the springs with new fresh springs. I am guessing from the date on the barrel. Your Garand probably seen its last complete servicing in 1967 or 68. The Garand is a great rifle to shoot!! Good luck and again welcome to the forum.
