"BTW, there is no such thing as a gas valve on an AR."
Well, sort of. All of my hosts have adjustable gas blocks or adjustable piston systems.
I wouldn't say "there's no concern" when adding a suppressor to a DI gun but it's not likely to explode. There is a concern that increasing the back pressure can cause undue wear and tear on the components so many users swap in a heavier buffer or adjustable gas block(and some don't). If the residual barrel pressure is excessive, the bolt may not close properly and may even cycle a "double feed".
