they are uncommon because they pricey for what they are and not terribly popular. i doubt they will grow in value. you can get a lot more rifle than a sig556 brand new for 1200$ in a more versitile AR15.
they sell new/slightly used from 900-1200$ on gunbroker
blue book has a lot of adds for diffrent options. depending on the exact version he has it could be worth more than 1200$
im not sure if they work with regular AR mags or not
i didnt care for the feel or the placement of various controls. purely personal pref.
