Whats needed to attach vertical foregrip to MAX 11-15 handguard?

[opee]

Bought a GPS-02 Grip Pod to attach to bottom of 11-15 handguard, but realized there is no picatinny rail on bottom. Any suggestions on the part I need to acquire to be able to attach my foregrip to the handguard?

An Mlock rail section. That's it.
