I am once again prostrating myself before the fount of knowledge. My current new toy is a Howa 1500 in 6.5 Grendel and I am interested in a muzzle brake. Unfortunately my barrel is not tapped and I heard about clamp on brakes. A quick search shows they are not chimeras but real devices. Has anyone tried or seen one in use. They appear to be custom fit with the measurements you send them. Do they loosen up? Are they concentric? Do they choke the barrel? An I/net search reveals several mfgs and a company called Witt Machine has a great return policy. They'll buy it back including shipping. Any input is appreciated.
As always, may God bless and guide us all.
