I don't come to this site for information on AR rifles.
But, if I did, I would simply use the (new, improved) Google search feature to see what I could find.
Entering a simple "AR" (typed exactly that way) I got this page of results for the Cast Boolits website.

Anybody asking for a dedicated subforum because he can't find anything in the present configuration should probably be required to turn in his electronic devices to the computer police.
