Call M&A Parts. I posted on here looking for an 11.5" upper, and got a whole kit (Barreled upper w/ BCG + CH, stock assy, and LPK) for $480. They dont have much of the non SBR lengths in stock, but had some 11.5's and 10.25's IN STOCK, as well as extra LPK's, of which I got one of those too. They said 2.5 weeks until it ships, and most reports I've seen is they are spot on, maybe a few days earlier, with their ETA's.
