The 15x1RH threading on the MR762 makes it difficult, if now impossible, to find brakes for it. I know of the PWS brake that HKParts.net sells, but are there any others?

AAC makes a 51T flash hider and Battlecomp will custom thread a standard or 51T brake

I have the Ebi-Arms - it works great in the reduction of muzzle rise but it's loud as heck - it blows all the gases to the back and the sides - (but it looks really really great

) will post a picture later

How difficult is the PWS to install?

It was harder to remove the existing brake than to install the PWS. It has an internal crush washer and it is super easy to time .

Excellent, and thank you.

Now, what did you have to do to get the present brake off?

I want to do all this before I fire it even once.

I had my gunsmith / transfer dealer remove the flash hider. It was brand new and never fired when it was removed. If I recall he said it was tough and needed heat. I installed it myself in a few minutes . Here is a pic of the final result

If feel you are able, before I would spend the time and money at a gunsmith try removing the OEM one. I have installed 2 of the PWS brakes on 2 MR's and as others have said, it was easy. They do generate some sideways blast effect. Not uncomfortable, but if you are standing next to them on an open range, you will probably want double hearing protection.

I agree with this recommendation . It should actually be easy to remove. However I suspect that some may have rockset or some sort of thread locker , because I have seen others report they needed more than just some force. I find it odd that HK would use anything since it is just a basic flush hider. Conversely, the one on my MR556 came off with just a slight tap of a rubber mallet on the wrench.

They don't use Rocksett, or any other thread locker for that matter. The OEM flash hiders are torqued to spec (60±5 Nm). Applying localized heat makes things easier.
