I have a few contacts at RRA. Lowers and BCGs are on indefinite backorder. If you can get through to them via phone, they won't give you any leadtimes. I did receive a box full of misc. AR parts within a month that consisted of forward assist kits, gas blocks, gas tubes, buffer kits, ejection port door kits, etc. I have 2 .223 barrels on order that I was told will be awhile. Basically RRA is waiting on BCGs and barrels for complete rifle builds and complete upper builds. Complete rifles will always take priority.
