Thread: AR-15 Suppressor - Adjustable Gas Block Required?

I’ve modified a few std ones by drilling and tapping. Fit a grub screw . Once set use a pin punch to stop the pin moving. I have dean maiseys adjustable one on one of mine and have fitted a few. They work really well. Are detented so no grub screw required which is what others are doing now in the us. I saw quite a few rifles at the last 3 gun match running too fast and had feeding issues on some fast 80 round stages. Using a heavier buffer on carbine buffer tubes definitely makes a huge difference as others have pointed out. I currently have the JP silent capture in mine and are pretty much the ducks nuts for quietness and fully tuneable for weight and spring pressure.
