Whoever quoted you $30 for a 10-round magazine is overcharging you:

I have found the Black Dog Machine magazines to be very well-made and reliable, but they don't hold the bolt open on the last round. But neither do the CMMG mags, unless you buy the optional bolt hold-open adapter.

If you really want the 20" rifle-length barrel, that is your decision to make, but I can tell you from experience that the 16" length is very accurate, and that seemed to be your primary concern from your first post. Also, think about the SS bolt. The premium you pay just buys a bolt that is (in theory) slightly easier to clean. My upper came with the phosphate-finished bolt with SS collar, and it is not difficult to clean at all.

Anyway, no matter what you get, I have a feeling you are going to really like it!
