Anyone looking for a heavy steel arca rail there is a new NC company called Kil-Spec making them. They don’t have a website yet that I know of but they are on Facebook. I’m going to pick up a 16” for my 6ARC AR to add some weight up front. They have some videos and weights and prices in their posts.
