P&S ModCast 235 - Open Mic Quarantine 12 Hosted by Ash Hess

Does anyone have the article or a link to the article Mike mentioned where the military looked at lethality of 556 compared to 762? I think he mentioned Faker as an author? I’ve been unable to find it on google and would like to read it.
In this episode at 43:36 into the broadcast, Ash Hess is holding up a handgun. Just curious what make/model it is. It seems modified in several ways as well.
