Haven't tried subsonic yet (have some Rem 220 gr), but supersonic 300BLK is easy to find (110, 125, 147 and 150 grain) and shoots great from my AAC uppers. I've shot lots of Fiocchi 150 gr.
That product does not mention the M&P10 by name and may no fit. Back up one level on MI's website and check out the two products at the top of the list (Mlok and keymod). They _do_ explicitly mention the M&P10 . . . even use as the keymod photo.
I'd post the link, but am typing this one-handed...
You need a handguard that fits a DPMS low-profile receiver. MI features the M&P10 on their website. They also note that you'll have to replace the ejection port cover pin.
Kodiakco,
How are your optics mounted? From the photo, it looks like the RDS's riser is clamped to the scope's mount . . . or maybe behind it on the rail.
Thanks.
