Suppressor Back Pressure Testing Part 2: 11.5" SBR vs 16" - SilencerCo, B&T, Surefire, Dead Air, KGM

In this video we follow up on our original suppressor back pressure test and ask the question, what happens if we drop down from a 16" barrel length to a 11.5" barrel? We found very interesting results, especially in some of the low back pressure suppressors such as the Huxwrx Ventum, B&T SRBS Ti and SilencerCo Velos. We use the Riflespeed gas controls to determine the proper amount of gas for each suppressor and so that we can create & observe repeatable results. See full list of suppressors tested below along with a link to the part 1 video.
