6MM ARC Build

[snipersteve]

I'm in the process of putting together a parts list for my 6MM ARC build. I'm going with a Proof Research stainless barrel and JP all the way back. My question is this, is a 6.5 Grendel JP bolt, a JP low mass bolt carrier, a Gen 2 Silent Captured Spring and a TBD adjustable gas block up front the right set up or do I need a standard BCG or something else?

If you plan on running it suppressed. I would suggest going with a standard BCG instead of the low mass. Should be easier to tune and be reliable.
