It's an "action grip" by Axius and it sells for $14 Cdn. They've got another one very similar by Bell but it doesn't have that fake leather grain to it. I dunno -- makes it look cheaper (and it is -- only $10). Personally, I like the grainy look better. You can get any colour you want as long as it's black. The main reason I got mine was to keep from chewing up the leather with rings, etc.
