AR-10

For me the tour was a bucket list item. I too dabble at building some. My favorite to this day is a old colt trooper 357 I was competing with (think early 80s) I bought a Barrel blank and milled flat sides vent rib and did the threads etc. it was stretching my ability. Thing weighed a ton when finished. But I could get on target instantly for 2nd shot result of the barrel weight. The technology today makes those kind of solutions comical now. But back then it was innovative, but so were bell bottoms!
That is really cool. Do you still have that barrel?
Yea technology has changed the game that's for sure but there are still old school guys out there that remember stuff like that. I did most of my learning reading old books that talked about old ways of doing things. Then when I talk to newer gunsmiths they think I'm crazy because things are not done that way anymore. I read this old gunsmithing book and the author wrote about setting a rifle barrel face back...with a file!!! Holy cow that is just incredible to me. Now I would never try this but it blows my mind that they used to do it that way.
