guys-
i'm slow when it comes to ARs but i do have a question.
I have a S&W mp15 carbine in 223.
I just bought a 6.8 barrel in rifle length along with the bolt-gas tube.
I want to buy a Hogue free float handguard (m:15008) but i can't tell if it is rifle length or not, do you know?

also- do i need to have any special adapters to mount this handguard to my rifle? (Free float barrel nut?) (tools)
