They probably mean they are at a company right now that has a company wide intrusion detection/prevention system that is protecting the whole network from trackers. If its a network wide thing, people often call that hardware when it's really just specialized hardware running some software.
Nevermind, I misunderstood what they meant. What they meant is there are trackers that fingerprint you based on your hardware to identify you even if you wipe your computer.
Must depend on the range, the two indoor I've gone to were both pistol and rifle ranges but there may be some limitations on the caliber on the rifle I don't know. For rifles I just wait for outdoors and just use pistols at indoor ranges.
If I had a full size pistol I'd probably put a red dot on it, my carry right now is a sub compact which I don't even think a red dot would fit without milling.
On a concealed carry it would just add unnecessary bulk. If you put them on a full size like the P320 for example then it would be beneficial. You just would need a different sized/custom made holster.
Got my own range at my ranch...broken up to different areas of the property, up to 50m pistol, Rifle range up to 150m and a LRS range share with my neighbor up to 600m...all of them with a hill as a backstop.
