I know three cops that have orders pending with RRA. Supposedly LE has priority for delivery. Between the 3 of them they ordered 2 .308 rifles and a stadard A2 with 20 inch barrel. It has been close to a year. They ordered shortly after the election.
I have noticed that RRA parts available from dealers seem to come in waves. I haven't checked recently, but for an example it will seem like no one will have lower parts kits, then I'll see a bunch available.
I think one of the biggest hold ups for RRA has been barrels.
