I'm probably using incorrect terms.

I know the barrel nut is installed, and the rail is over top of it. The base of the rail where it meets the upper has a section where two hex screws secure it.

But I got the handguard/rail dirt cheap and idk if it's intended to tighten until the metals wings clamp together, or if there is a missing piece that is supposed to go between them, like a washer or something else to provide tension.

Many don't. Some have a spacer. If it's cheap, likely not. There should have been a torque spec to hit. If not, we can infer a torque spec from the size of the bolts.

Lemme know if you need any more help. I've built a few and repaired way too many ARs.
