Has anyone switched out the gas block on a Larue Ultimate Upper kit for an adjustable gas block? I am running Silencerco Hybrid suppressors on my two uppers and I am getting a lot of gas blow back. The guns run so smoothly I am hesitant to mess with their function.
Currently though, the ammunition left in my magazines are really dirty after just a couple shots.
