This video debunks the myth that a staked AR-15 castle nut is permanent and cannot be removed. The presenter demonstrates that a staked castle nut can be easily loosened with an armorer's wrench, explaining that staking's purpose is to prevent vibration-induced loosening rather than permanent fixation. The video also advises replacing the endplate when reinstalling a removed staked castle nut for optimal results. It references other videos on the necessity of staking and the correct staking technique.
