once led to a wonderful page that answered that and sbr and sbs and silencers and so on.
that page no longer shows up.it was simple and straight forward.
now it links to another web site, the same info "might" be there, but i dug around alittle and did not come up with it.
just letting "you" know, it was nice to have, and i used it several times to answer questions from other forums, not normally fire arms sites.
