Wow..........a Grendel SBR! I have 2 5.56mm SBR's I use a can with just to control the noise, but I really cant imagine how much flash-bang-noise you get out of that or velocity? Have you run into any cycling reliability issues with the gas system? What kind of spring and buffer are you running?
Sorry for the questions.......I was just curious as I plan to build a 300 Black Out SBR soon.
