View Full Version : Muzzle brake removal on AR-10

I’m thinking of getting an Armalite AR-10 with a muzzle brake. I would like to remove the brake and but on a flash suppresser. What is the procedure to take one off?

I just posted this somewhere else, but in case you don't see it...

I thought I would share my experiance because I am sure many will be doing this soon.

It started by me trying to find out how the thing was actually attached to my rifle. I figured I could heat it up and wrench it off because I thought it was silver soldered in place, but I was wrong.

I went to AR15.com, posted a picture, and asked how these things were put on to make sure, and I got a reply as follows:

You can usually find the location of the pin and, using a Dremel with a cut-off wheel, grind away on the brake until you can get the pin out. At that point, you unscrew the brake.


So, I figured, easy enough... WRONG!

To start, I noticed that the finish wasn't quite "perfect" on the underside of the brake. It was not one of the flat sides, it was the fat, rounded side, so I figured I'd start there...

The thing had one "pin" holding it on, but it was far from being a simple "pin" -- it was a set screw. I managed to Dremel around the thing enough to get it off. It took about 1 hr. Some of that time was spent exploring the rest of the thing to make sure there were no more screws. I knew I had the right side though because the cut-off wheel "sparked" differently.

I basically had to cut a square around the thing and get it wiggling and then twist it out. It was a pain in the ass to say the least, but, now I have my A2 FH on. Gonna be getting either a Phantom or Vortex soon.

Here's a "post-op" pic:
