I never used them until recently and now I love them. I've been teaching my son to shoot an AR and it's nice to be able to verify that the bolt is locked back from a distance. I just use the ones that came with my CMP rifles.
To a much greater extent than most mechanical devices, firearms are terribly unforgiving of any overconfidence, complacency or negligence.
