From Bearing Arms:

So, YouTube appears to have informally implemented a new, unspoken policy (i.e., I could not find this in the content guidelines) whereby it will demonetize videos which aren’t shot in a “controlled environment” such as a “shooting range.”

This raises a lot of questions, not the least of which is:
How does YouTube determine what usage is improper? Is there someone at YouTube with proper training on safe gun handling who will implement these policies?*
How will they know when someone is in a “controlled environment” or not, and who has the authority to reach that conclusion?
Is a shooting range, in fact, safer and more “controlled” than the creator’s private property such that this policy needs to be implemented, to begin with?
WHAT IS A MODIFIED WEAPON?
Who do you think you are?
What gives you right?
