Hello,
I have been trying to figure out what gunsmiths mean by "unitized" gas cylinder. Does this mean that the spindle valve assy. is spot welded, or somehow made unable to rotate? Also, what is a "National Match" ferrule? What can possibly be done to the front ferrule to make it "National Match?" I keep hearing these terms and can't find ANY information in regards to them. Please forgive my ignorance on the subject matter. I'm fairly new to the M1A/M14 world.
Thanks in advance,
Jim
