Please note: These barrels SHOULD cycle most supersonic ammunition without a suppressor; however, they will cycle most reliably with added back pressure provided by a suppressor or linear compensator.
Furthermore, if you do not plan on using a suppressor and would like to shoot light powered ammo, you can use one of our reduced power buffer springs and one of our lightweight carriers. The reduced mass in the action will help cycle with less gas.
In our testing, we were actually able to cycle subsonic ammunition without a suppressor, but with our reduced power buffer spring, our lightweight carrier and a linear compensator.
