You got it bad! How many times have you been back to look at it? Saw a stainless S and W 44 Mag Classic today with Cherry wood grips. I immediately left the store before I did something rash.
Got something, but I am afraid it might send Angel to the ER. This is called a mud puppy. It secretes a slime that is caustic and can be toxic to small fish. A buddy of mine caught it in an ice fishing contest.
Dubya, is the Minnetonka gun club still near St. Francis? My Father belonged to it when it was down east of St. Bonifacious on Hwy 7. That is where I learned to shoot.
Shame, as an AR10T is an awesome rifle. I would contact Armalite tech support via email, and describe the situation to them. They can tell you what you need and how to get it when you move to the US.
My first suggestion is to go through the 308AR website and the 308AR forum. Go through the archives and you will get your questions answered and learn a fair amount about all of them and which direction to take your build. You will know a lot more that way then having one of us try to answer a really involved question in ten sentences or less.
