I’m sure SilencerCo’s “How Its Done” video will find favor amongst many members of TTAG’s Armed Intelligentsia. I’m equally sure that most potential consumers couldn’t care less. You put the can on the end of your shotgun, load it with up with shot or slugs and Bob’s your uncle. By the same token, I bet the majority of people who bought the ill-fated, poorly constructed Remington R51 have no idea what a Pedersen roller-delayed blowback action is. [Click here for the video.] That said, how much does the average American need to know about firearms function. I wish I had a dime for every time I’ve heard “GLOCK…you pull the trigger it goes bang.” So how much do you know about guns (mechanics, ballistics, metallurgy, etc.) and how much should a gun owner know?
