3-inch launcher muzzle ball/breech ring interlock (SUBSAFE Boundary).

Here's something for you to keep an eye on. On several recent surveys, I have found a problem with the muzzle ball/breech ring interlock tail rod. On these units, the tail rod could be turned by hand (actually unthreaded if desired). This problem could prevent proper operation of the breech ring and effect travel of the muzzle ball valve. By design, the tail rod is not staked or pinned in place. Instead, it is only held in position with "lock-tite." When were your launcher barrels removed last for muzzle ball valve repairs?
