re: #364 CIA Reject

Can you adjust headspace on the M-2?

Yeah, there’s supposed to be a gauge that comes with the receiver, held on by a metal chain. When changing barrels, you screw the fresh barrel up to where it touches the gauge, then back off to the next detente. A WWII/Korea infantry vet taught me how to set it without the gauge, if you really needed to.

Note to all: my experience with the .50 is now more than 40 years old.
