Hi, long time reader and big fan of the forum. I've always being able to find answers on the forum without actually having to post a question myself until now. Purchase a couple of new lowers a week ago and was wondering if I can SBR them? I do have lowers I bought pre Oct 1st and I know for sure you can SBR those, but what about the ones you can purchase now? Can they be registered as SBRs? I'm getting different answers from a couple different people so your help is appreciated.
