Is the Mossberg Boron Nitride gas piston worthwhile?

[JCinPA]

I have a plain 930 original piston, and I’d love to get the SBE Precision piston, but it seems they are scarce. Would you recommend an upgrade to the Mossberg coated part in the meantime? I know I’ll need the outer ring if/when I get the SBE, but just wondering if this upgrade is worth it now. Does it reduce the need for cleaning as much as the SBE, or not?

Not going to do much, it's not designed like the SBE piston which foregoes one gas ring to help blow out carbon from the piston
Also on the 930JM the mag tube is also NiB coated to help stay cleaner under a heavy firing schedule
