M&P 15 Tactical M-LOK Internal diameter

[Yugnat]

Hello,

I can’t find detailed specs for this gun and I need to know what is the internal diameter of the slim M-LOK handguard. Maybe someone here can help me?

Thanks

If you're wondering , will it fit the Sport II? The answer is yes.

I’m wondering wich suppressor may fit inside for a 300 blk build

Opening is roughly egg shaped. Mine measures 1.32 at top, 1.81 at widest, and 1.375 at bottom. Approx. 1.67 from top to bottom points measured. Mine i s the m-lok sl.

Thanks for taking time to measure yours ! Unfortunately the one I’m looking at is this one :
M&P(R)15T Tactical with M-LOK(R) | Smith & Wesson

If someone owns it and can tell me if an 1.6 suppressor would fit inside the handguard that would be great !
