Oh, and as far as a price tag you should find them ranging from $650 to $950 depending on your source and whether you' re trading and paying the balance as compared to s straight cash sale.
Also when I acquired mine it had to be special ordered as no local shop had one and Bushmaster at the time was out of stock and making new ones. They were also filling a government contract for these rifles which delayed public sales. That was a few years ago so their availability has most likely improved since.
