What kind of issues did you have shooting suppressed? Mine hasn't had any problems shooting suppressed. I use it for as a host for my Phantom LT.

Here's my thread in the issues.
My final configuration is heavy buffer, heavy spring, adjustable gas block, and enhanced extractor spring.
I have not shot it with the extractor upgrade yet, haven't been able to access my suppressor for a bit. But hopefully I will soon.
My M&P10 is an early production model (KN 04xxx serial #). It does not work with those handles. With the BCM handle, or the Strike Industries, it won't even allow the BCG to go into battery. With the Raptor, the BCG will go into battery and jam up TIGHT, so tight that tools are required to get it un-stuck. (These are all AR-10 sized handles, I own all three because I have several .308 AR rifles.) I can only guess that S&W fixed this incompatibility with later production. Mine works fine with the OEM charging handle, so I can't call it defective, but no other handle I've tried works. YMMV.
With a little filing, the BCM can be made to fit.
