The only problem I have with testing a locking bar is that to test it on my axe feather includes putting a speed 900 on 25V into a full stall probably blowing fuses potentially speed controllers etc. I can understand for CO2 systems where a robot may not be at risk from it's own locking bar but in an electric weapon the locking bar can actually inflict damage onto the motors and circuitry of the weapon it is meant to hold.
