I assume he is hearing buffer spring inside buffer tube noise as well as the action cycling noise ?
If so the Jp silent capture should help some. It’s definitely is quieter that traditional setup. Not exactly cheap though
I don’t believe anything you can do about the cycling noise short of making sure lubed properly. although running plastic mags seems to be quieter to me than aluminum or steel mags. Although that could be in my head as well
Take suppressor off and shoot it. You will see quickly it isn’t defeating the purpose of the suppressor.
