The muzzle brake I ordered from Witt Machine came in on Friday and I installed it this afternoon. Quality it excellent, in fact it is very good looking. I had the cerakote finish is very smooth and even. Installation was a breeze and the only difficulty was keeping the brake aligned during installation. The provided instructions were more than adequate to the task. You do need some blue loctite as per the instructions and you do not want to over torque the bolts. Here are some pictures and I will post the results of recoil reduction as soon as I can get to the range. If it works it will be well worth the C-note it cost.
