I've been in email contact with Laura at Young Manufacturing and it appears they will have new BCGs in stock in a week or two.
They will have standard and National Match in both AR-15 and M-16 versions in chrome or standard. From what I understand, the National Match carriers are 1/2 oz heavier than their standard carrier. Their website and phones are down, but they will accept CC orders via email (NOT a method I would use) or fax. Several posters on ARFCOM have recently received BCGs from them and state their quality is as good as ever. And their prices are pre-hysteria.
