Barrel nut not included - Trinity Force MX-15 M-LOK Free Float Rail

Is a nice looking handguard but was disappointed to see that it didn’t come with a barrel nut so now I gotta go through that hassle trying to figure out what’s gonna work. It even said the barrel nut was included under the question and answer section but they lied I did not receive which is aggravating cause what’s the point of getting a handguard with no barrel nut it’s really kind of pointless.
