Quote: Personally I would start with a 26 inch bbl. You can always cut it back.
True. The only problem is that this rifle will be iron sights only, so a bit harder to cut down once it's built.
Quote: I've seen the YouTube of the 600 OK with and without brake and there's no way I would shoot one without one.
Could you share these links, I don't think I have seen one without a muzzle break. I have no plans to put a muzzle break on mine, but I would like to see the difference.
