I am working on putting together a rifle that is a fairly heavy .308 bolt action built with an eye towards accuracy. I picked up a heavy barrel for it cheap a while ago, but it turned out to be threaded and so I need to put something on the end. I'd love a can, but it ain't happening in this state. I can just stick a thread protector on there until I figure it out, too, but what fun is that? A flash hider seems kinda unnecessary. So, it's a muzzle brake.
What should I look for in a brake? Any recommendations? Assuming the materials are the same, are high priced ones that much better than cheap ones?
