At the M-14 forum I was reminded that besides Fulton Armory as a source of supply there is also Smith Enterprise. And I leaned a new onw. LRB Arms.
One of the best general Gun Forums was started by the inestimable Oleg Volk. The man is great photographer. He started The High Road forum in 2002, but, apparently, there was some recent trouble. One of the admins he trusted may or may not have managed to hijack ownership and may or may not have sabotaged that great resource. Details from one side are here, and about how to maybe help Oleg out. I certainly don't know the particulars, and now that lawyers are involved I'm keeping my nose out of it, other than this. I will say Oleg appears to be a nice guy, by all estimation.
