I have been looking around for ideas also. Like the NF stuff and the ACOG's, but they are pricy and I am not sure I want to drop that kind of money right now.

I have been spending some time looking Burris. They seem to have some good options. They XTR line is made in the U.S. and the MTAC looks to be the same, but made over seas.

I have a Burris Fullfield II 3-9 on my hunting rifle and have been happy with it, so I may try something from the XTR or MTAC line on my AR.
