LGS messed up my handguard?

[Apparition]

I offered to give them the barrel nut wrench that came with the handguard but they said they already had one.
Hopefully they give me a call tomorrow. I may have to drive in to talk to them in person and try to get everything straightened out.

The barrel nut wrench should have no impact on the tabs on the handguard. Once the nut is installed the handguard slides on and then you clamp it in place. Unless they used the handguard as the nut wrench.
