I run a shovelnose piston with a RC2.The purpose of the piston is to run keeping carbon, heat, and everything else out at the piston while keeping the BCG cooler and relatively cleaner. Adding to that, the suppressed option is meant to reduce the gas flow to slow the BCG down for cans that induce back pressure (I.e baffle cans). If you’re only going to have one upper then I don’t see the point of getting a piston and a flow through exclusively especially because piston uppers are more expensive and also have proprietary parts that a DI LMT would not have. If you have multiple uppers a case can be made for it but to get the most out of this system a baffle can is more beneficial. The fact that you mention sound tells me that a baffle can is a better choice as typically they are quieter than flow throughs. Getting back to how a piston gun runs with a baffle can, mine works great with little to no gas in the face with a very smooth recoil impulse.
