I am not sure if this needs to go in this forum or over on ARs but I have a question about shooting a suppressed AR...
Finally got my first can after an 8 month wait, shorter than I anticipated so I was happpy because I waited 11 months for my SBR stamp. Went out and shot it today with my sub-sonic 300 blackout SBR, 10.5" barrel. Gun cycled flawlessly but I did notice the ejected casings had a lot more fowling on them than when not shooting suppressed. They were almost sticky to the touch. I assume this is from gasses blowing back due to the can...is this normal and to be expected or do I need to make adjustments somewhere (more or less powder, different powder, adjustable gas block)?
On a different note, even shooting subsonic loads it was louder than I would have guessed.
