Fortis Adjustable Gas Block with Flywheel Technology .875

Our adjustable gas block was designed with precision in mind. With a positive click detent and visual gas setting indicator, there’s no more guessing on how much gas you’re letting into your system. Other competitors require the user to not only guess at the adjustable gas setting, but they also use a screw that can potentially back out or not give the user their desired precision. Our Flywheel™ technology allows ultra reliable, adjustable settings that’s user friendly and easily servicable. Leave the guessing behind with the Fortis Adjustable Gas Block with Flywheel™ Technology.
