M1A Muzzle brake

I am looking for a better and shorter muzzle brake for my M1A Squad Scout. What are my options?

This is the 18.5" barrel Scout Squad, right? I ask because the SOCOM 16 is a bit different.

I have no personal experience with these companies or products, but the SEI brake is supposed to work well from what I’ve read:

Brake.

Yes 18 inch barrel.

I was waiting for that, thanks.
