The Surefire Brakes are classified as "Essential Military Equipment", I tried ordering from Brownells but no go. I spoke with someone IRUNGUNS and apparently they'll bring them in for you if you order off there US site.
Check with Wild West Shooting Center. They can order it for you.
I put a Badger FTE brake on my 308 and it made a noticeable decrees in recoil. I would highly recommend one!
alberta tac makes a sweet break, my 80lb nephew put a full box through my 308 and asked for another mag with a big smile ear to ear!
I would agree about the brake from alberta tactical I ran one on my .300win mag and also on my.338 lapua mag easily going out and doing 50+ rounds with no sore body parts and more importantly holding the sight picture
