I received the muzzle brake and extension over the weekend and was anxious to get it installed. It was one more step that needed to be taken care of before I could legally press the barrel into the receiver.
I decided to get both the extension and the brake. The reason being, if I want to do something later on, whether it being installing a different brake or a suppressor, it would be difficult to remove the brake if it was silver soldered directly onto the muzzle.
CNC Warrior’s brake doesn’t disappoint. You definitely feel like you get a lot of brake for what you pay for.
The brake is notched in the rear to allow the timing pin to time the break so that it is properly aligned. However the barrel extension is not. Since I wanted to used the brake and extension together, and I wanted to make sure I wouldn’t mess up the timing, I decided to transfer the notch from the brake to the extension.
I took the extension and the brake and screwed them together. Then in a vise I used a file to mark where the notch needed to be cut in the extension.
I don’t have a mill, the next best thing I have is a Dremel. Gunsmiths everywhere just cringed.
At the end of the day I worked slowly and took off a little material, checked the fit, and then took off a little more. It took me all of about ten minutes to get things to where I was happy with them. The metal was soft and the silicon carbide grinding point had no problem cutting the profile.
I applied some silver solder paste to the threads and some cooling paste inside of the barrel. It took another five minutes and the extension was permanently attached. It is now a legal rifle length barrel ready to be pressed into the receiver.
