Im wanting to get a muzzle brake for my 6.5-284 and my 260 rem. Im wanting a surefire muzzle brake. I would have to get the 30 cal because surefire doesn't make a 6.5 mm. Do i need to get a 6.5 mm muzzle brake or will a 30 cal muzzle brake work just as good as a 6.5mm muzzle brake. Also would yall recommend some 6.5 mm muzzle brakes. I would appreciate the info. thank yall
