The Truth About Back Pressure and Cans || MATH WARNING

Math warning, for anyone who is sensitive today we are going to talk about the science behind how suppressors work a bit. Specifically why do suppressors increase back pressure. What I mean by this term that is often misused is these devices can cause suppressor gas blowback or suppressor gas in the face. Many will equate this to an increase in back pressure, but this is simply not the case. This phenomenon is prolific enough for many companies to come up with a variety of products such as charging handle mods and adjustable gas blocks to mitigate suppressor gas. This video is based on the basics of suppressing the AR-15 but the same model can be used for any other direct impingement system. SO lets dispel some myths about suppressors.
