Good suggestion. That's what I'd do too. Seems strange that things are not working with either of them, unless they were both put together wrong by Brownells, or there is a similar defect. Figuring out if there is a blockage in the gas block or barrel is pretty easy to do without having to take schidt apart too. I've personally had a left hand stag 24" Upper and it ran smooth as silk. No issues at all and I tried the upper on different lowers, with the same brand (black rain ordinance). Still ran flawlessly.. Dwell time did not affect anything even with a lower I tested that had a carbine buffer. The rifle length gas system on that upper was very smooth and soft shooting.
