Actuall, the Grand has an eight round clip. It is kinda heavy, but not all that much more than a M-16A2 heavy barrel.

I would love to have a Springfield Armory M1A, just 'cuz I loved the M-14, but they are pretty pricey.

Altho I am not a fan of bugging out, and am not sure that a long arm goes with a BOB at all, I suspect that any quality bolt action in .308 would do just fine. And a bolt will probably stay off of the anti-gunners hit list the longest...
