Is it staked and do you think there's a gasket seal between the key and carrier?

Chad addresses loose carrier keys with his reverse torque test in the video I posted. Loose carrier key or bad or worn gas rings, are the first places I will look. Some manufacturers seem to have a higher rate of problem parts than others.. What many people don't always understand, is an AGB will only restrict the existing barrels port pressure. If the port is under sized to begin with, an AGB is useless.https://www.youtube.com/watch?v=xKyFt3xQC9E
