15 inch option is too long for the m&p 15-22 - NcSTAR Vism M and P 15-22 Keymod Free Float Handguard

The 15 inch option is just too long with a stock barrel. With the provided barrel nut tool, you won't be able to tighten the barrel nut with the new hand guard, since the tool is too far in the guard to wrench the barrel nut. The muzzle end is also covered, so with a stock muzzle break, you will not be able to tighten it. The instructions were not helpful at all, and the video it has linked in the instructions isn't even for this hand guard at all. The product over all is great, just the listing saying it fits is wrong. Will be purchasing the 13 inch option.
