It's a nice atty , but I haven't settled on a build for it yet , I'm using it on my SVD so I'm not subohming it , I can go as low as .8 on that mod with it but I think the airflow needs to be opened up on it before I go that route with it , no fluff just straight up , I picked this up after reading your post about building yours without the fluff .I've missed a lot. How long ago did you get the heron? Do you like it? Using fluff or straight up? How hot you running it? I'm so behind. *********** I posted this after reading he first sentence and saw the word Heron. Then I read your post. My bad.
