This is the titanium version of my magnum 5 port that has been a hit with the ELR crowd using cheytac cartridges. The titanium saved 6 oz from its stainless version. Anything burning over 100 grains of powder will have its recoil severely reduced with this brake. The first port is 90 degrees to direct the backblast/concussion away from the shooter with the proceeding ports being angled to further reduce recoil. This results in a very shooter friendly brake that has top level recoil reduction as well. The gun literally won't hardly move with 338 lapuas.
