well, i got a few barrels over the last year or two that have no markings on them. they have been good. i was just thinking that it is kind of strange? i guess that is the way it is? like i got some a&b barrels and they stamped the cal on the chamber end. got a custom barrel with no markings at all. guess i would feel better if the cal,twist and maker where on it? you know that warm and fuzzy feeling. lol!!
