Why?
Plug something like "gun review for _____" or "best self-defense guns" into YouTube's search, with a new/incognito (or boomer/normie) account, and all the big names will pop up in the first page of results; Hickock45, Forgotten Weapons (for anything vintage), IV8888, Sootch, TFB, Honest Outlaw, Yankee Marshal, and Colon Noir (if your youtube sub/search history is full of nigger shit) will make up the first two pages of results.
Attempting to make an OP like that would quickly devolve into slapfighting about what guntubers are shills or annoying faggots, and which ones are insincere or grifting assholes.
This thread has that in spades already; why do the extra work, when it'll just get merged or shut down anyways?
