I could go to [s]$870[/s] $800 without the hogue grip or 6-position stock.
However, as an FYI, to maintain the rifle's pre-ban status (by ATF regulations/opinion, anyway) I would have to at least ship the lower with a telescoping stock and pistol grip...so I'd just install an older 4-position unit I have on hand along with a standard A2 grip for the [s]$870[/s] $800. What you do with those parts once you receive the lower would be your call.
[blue][i]Edited to add = the 4-position stock I mentioned above is the plastic style, but it's not one of the cheap made it China POS's.[/blue][/i]
