Well my friend who just recently purchased a S&W MP 15PS and I was wondering if by chance LT 7" Handguard fits this particular gas-piston system?

I'm trying to steer him the way of LaRue but  I do not know if the LaRue Handguards can accommodate the Gas-Piston system within the MP 15PS.

Thanks y'all for the help,

The 7" hand guard is for the carbine length gas system and leaves the gas block exposed..
I don't think there is enough room for the gas piston and spring under the guard. It is a pretty tight fit.
If you have a height and width measurement I can see if it would clear. Also get the diameter of the gas
piston to make sure it won't bind in the barrel nut.
