Building an 11.5" AR, What muzzle device would YOU put on?

3/4" sir from back end of threads to the first port hole

Thanks! It looks like the some of the ports would be obstructed by my rail . No griffin arms comp for me.

I tuned my Effin A comp for my 10.5" NEA AR this weekend. This was one step away from my final adjustment for tuning, but it still shot flat.
