Got an adjustable gas block, it’s all tuned up and running nice. Seems like overgassing was the issue. I didnt know AR’s were that sensitive. I’m glad it wasn’t something serious.


Yeah they can be. Read a lot on 300BLK and generally it's suggested to get an adjustable block when planning to shoot suppressed. One suggested opening up the gas port to a larger size as well if I remember right as sometimes they will be undergassed when not shooting suppressed. But being over gassed is even worse when they have the 16 inch barrel with a pistol length gas system.
