Yes, it will work. It's about the only one that will work on a .308 AR. Unless you custom-machined a .308 AR upper, the MagPul BAD lever won't work on them. It's a clearance thing. By now, there might be a billet upper from a manufacturer that has a recess (in the upper) that would allow the BAD lever to work, but I haven't seen any of them yet.
