Right now just on my 16" 556 upper. Yeah I was thinking about getting a .30 as I'm sure I'll eventually get a 300 upper. Don't mind messing with the rifle as long as it doesn't require rocket surgery. Mix of shooting indoors and outdoors so you wouldn't recommend a can when indoors?
Do you know the gas length of the upper?
The indoor vs outdoor question was more for recommendation purposes. I always shoot suppressed, it makes a massive difference. I also recommend still wearing hearing protection, especially indoors or near reflective surfaces. Like an overhead shade cover, wall, etc.
Huxwrx and other "flow through" designs sound excellent out in say an open field but sound significantly louder indoors or around reflective surfaces vs more traditional non-flow through designs.
Okay just to start the process of recommendations. But these can change depending on your answers.
