It’s crazy and I never would have believed how much that little metal lip reduces gas in my face, but they really do. I have G and BCM ones. (And yeah, for shooting suppressed).
I placed some painter’s tape on the receiver and charging handle, squirted a bit of RTV sealant and formed my own little gas buster gasket on my ARs. Makes a huge difference suppressed.
