Re: YO DAVE trigger kit - CZ 455 install
i'll try to mic the tubes for wall thickness, but i can tell you (honestly) i'll probably forget.
if you go to the yodave site and use the "contact us" you actually get a response including whatever specs. i asked on there a question, and actually got a quick and honest answer. that route would probably be the best.
i know i've seen the measurements on a forum somewhere, unfortunately i can't recall which one. either rimfire shooting, RFC, or steelchickens was the forum.
i think (but not sure) the supplied instructions had the circumferances, but not sure of the wall thickness. i'll take a look at them later today as they are in easy access and post 'em if they are noted.
...that's what i like about toe tags; one size fits all...
