Wouldn't sit flush - VISM AR15 M-LOK Carbine Handguard

The handguard fits but it doesn't fit straight. You can see that the handguard twists toward the right. You can see it hugging the left side of the front side post and when you look down the top rail from the charging handle you can see that the top rail on the handguard where it meets the rail on the upper receiver is not flush at all and slightly lifted on the left side.
