So is it as simple as the Noveske Switch Block, only you're switching weights instead of adjusting the gas block? How is the gas blowback when shooting suppressed? It's great that this is a way to make both reliable. I'm about to add this to my arsenal as well as a superlative gas block. I'm hoping with both that I don't get carbon every freaking where when shooting suppressed, and that it is a reliable system.
