So I have one S&W M&P 15 and M&P 10. I have been trying to find free float tubes for the AR-10 but not alot of luck. Very limited info out there on this one since its so new. So I took the handguards off side by side and to my surprise, it looks to be AR-15 mil spec at the barrel nut end. Can I use AR-15 parts on this? I have never done any mods to an AR so that is why I am asking. here are the pics. I ask because usually the 10 stuff is completely different and seperate from the 15 stuff. Maybe hand guards are not this time?
