You guys know more then I will ever know...or hope to but here goes:
I have a young machinist friend who wants to begin gunsmithing. He is of the opinion that the Marlin and other Barrel nuts are the pits. He is old school I guess and things a barrel should be threaded in and not have a nut to work loose.
Another friend, older bud, is considering a ML7 action in 338-06 with the bbl nut and a custom barrel.
I hate to tell tales, but what is the base opinion on the barrel nut from you who do this stuff and have field experience with them...?
