M1 Garand Magazine Conversions

by Walt Kuleck For those of us who are relatively ignorant and/or inexperienced as gunsmiths, could you be “technical” for a bit about the subject? What exactly is headspace? Where is it? What are the tolerances, etc? There are two ways to look at headspace. First, let’s consider the practical
