Abstract
Disclosed herein is a collar stop configured for insertion into well production tubing where the collar stop provides an interference fit with a collar recess disposed between two adjacent sections of production tubing. The collar stop may be utilized to provide a bottom hole assembly at a desired location in a well bore. The collar stop device is configured to lock once positioned. Such locking prevents accidental removal during high fluid flows.
