This is one heavy duty brake. Fits right over the sight of and mosin, securely mounds by 3 allen screws around the device as well as 2 that secures the mount behind the sight, requires no threading of the barrel. This does an incredible job for the hard kicking mosin. I recently had my mosin barrel threaded and no longer need this as an option. I've attached a link to the exact brake. Message me if you need more detail.
