I'll one up you on price, Granite Ridge Outfitters have them for $69.95 (http://www.graniteridgeoutfitters.c...nd-Rear-Sight-Set-Various-Colors-MBUS-SET.htm). Black and Grey are in stock, the others are on backorder. I have a set of FDE ordered and per their email should be available in about 10 days. We will see if they truly are legit.
