I went with the AR-10A2 (.308 has opposed to the .223)
Heck, I just picked up a Sig P220 (.45acp) this weekend.
I clicked on the link and found the - BUSHMASTER. How appropriate!
We can now tell libs we protect ourselves and our families with BUSHMASTERS. I love it!
A good choice, but for those of us that live in a city, the shotgun rules the ranges at which urban combat occurs.
I'm an advocate of the combat shotgun - semiauto, detachable magazine.
