Starting the build

[duckriver]

Just ordered this. What's your thoughts on rock river uppers?

They're pretty good. I believe some were made for them by FN. The one I have is supposedly one of them.....and it's for sale

I've sold 8 Rock River rifles. They were very well made and specifically requested by security I know @ one of the high security nuclear facilities. If I were going to build, I'd put a Rock on top.
