Prioraties lol, I'm doing the same just bought 1000 rounds of x39 and Im still waiting for my upper, but I wanted to get a good amount of ammo incase panic set in after the election. I like those Troy sights especially the rear. I've never used that style of sight before so I like the idea of the hashes on the rear. I don't plan on buying my optics for my arak till I got some extra cash or it goes on a sale hopefully. I'll probably end up buying a front from MWI, I've already got one of their rears.
BTW I see MWI has them in FDE
