does anyone know the inner diameter of this rail, i need to make sure it'll clear my gas block before i order it. thanks.
Wouldn't it clear any low-profile gas block?
I didn't find any specific info on their site.

me either, the block i have needs 1 5/8 min. inner diameter.
I'd send them an email for specifics since the handguard is a chunk of change.
