Today at my range while the outdoor range was "hot" a member walked down a couple stalls to me and asked me to open the "bolt" on my AR and keep it open. Ive never been asked this before while the range was hot. I just took the weapon out of its case and it was facing down range, safety on, and no mag in it when he walked over. I was at the range for less than 5 minutes setting up when I was asked this question and was loading magazines for my pistols and rifles waiting to put targets up. Both my pistols slides were open at the time, just not the AR. In my 10 years of going to numerous ranges Ive never been asked to secure the rifle I was setting up to shoot. Is this common? Some other members heard it and told me he was out of line.
