Standard black and clubfoot tan are the only ones left (both for mil-spec receiver extension). These are the older Modstocks which are no longer in production, as opposed to the newer iMod or eMod. Still a good, functional stock, and a very attractive option at $49. Bravo has been running this sale off and on for about a year or so; they must've had a crap-ton of them on-hand to start with!
