I recently ordered a Surefire Brake and found that the materials shipped with the brake were not too helpful as far as installation parameters. Thanks to Chuck V. this issue was quickly resolved. It would not hurt to make this a sticky for those who have questions on what needs to be done to install any of Surefire's muzzlebrakes. The key on the right side gives the dimensions necessary for each individual brake.
Hope this is useful information. If you need it emailed pm me and I will shoot you the pdf file.
Thanks again Chuck V
