If you go to your local Gander Mountain on Thursday morning, this is the day they get their truck and it is your best chance at getting one. They had the Carbon 15 for 799$. But it is a complete piece of garbage.
ive had a few, if u want a ar get a metal one, im sure some of the polymer ones function, but ive shoot at least 4 different ones whitch had problums, i think there junk.
