So, I just got this back from Ecco. Looks awesome. They are super nice to deal with and do really good work. Here is my question. I was planning on running an area 419 setup for it, but I realize that the original mount had a brake in the blast chamber, and the 419 will not. I don't know if I need to use a brake setup on this to protect the baffles, or if the 419 is good to go on this setup. It's easy to go either way, as I am also using Griffin Plan A on other rifles I have.
