Weight of FSB?

AR/M4 AR Technical Discussion

Does anyone know how much a standard front sight base weighs (grams are preferable?

I’m in the process of assembling a lightweight upper and wanted to evaluate a few options, e.g., weight of the FSB vs VLTOR low profile gas block + DD fixed front sight. Obviously the latter would require a FF handguard.

Thanks.
