If you’re using an adjustable gas block that can be adjusted easily, we recommend closing it completely when shooting 22lr in a 223/556 barrel to keep the gas system clean and the gas out of your face.  The conversion kit is a blowback actions and does not require any gas to be diverted into the gas tube.
