That's not my experience using an Adams Arms unfortunately - When using a suppressor with piston, cases and receiver end up just as filthy as a DI system. Suppressor soot comes from the chamber, not just the gas tube. The added back pressure when using a suppressor means as soon as the case unseals the gas flows back around the case into the receiver. Same spit in the face for left-handers, same dirty unfired rounds at the top of the mag.
Went back to using an adjustable DI system for just that reason. What's the point of having a heavy, chunky gas block if it does nothing more than a DI system. Plus I was limited with using a handguard that is only as long as the block.
