You can pick up a CZ for about $500 versus a Dakota for $2500. And people wonder why Dakota is in bankruptcy.

I have heard some great things about Granite Mountain. And Empire.

I ran across a good priced 510 caliber barrel, old but still new in the box. I passed though, since it was just a bit heavy. It was a 36" barrel for an M2 Browning Machine Gun!
