Bam!
Hold your horses, chief I'd argue that I don't need any of the things he mentioned except maybe a thread protector and the tall night sights (both of which I had to purchase separately for my USPct). But then, too, I'm always on the lookout for deals and I got mine as a brand new LEO package (extra, 3rd magazine) for $815 shipped, over $250 cheaper than an FN Tactical. Granted, I got lucky but it's been known to happen from time to time.
