The Sharps Bros. Upper Receiver Ar-15 Billet W/dust Cover will be compatible with the Sharps Bros Handguard. Due to the problem you are having fitting the handguard to the Sharps Bros. Upper Receiver Ar-15 Billet W/dust Cover I recommend contacting Sharps Bros. in regards to what other handguards they recommend. From what information I could find the SLR handguards like the ones at the link below have worked with this upper receiver.

Yes, the Midwest Industries AR-15 Free Float 1-Piece Combat Rail Handguard will work with Mil-Spec AR15 upper receivers. So it will work with the Sharps Bros. Upper Receiver Ar-15 Billet W/dust Cover.

Yes the SBUR04 will work with that rail. The SBUR04 has a mil-spec front end. This product listing here though is for the SBUR03 - which has an enlarged front end to match the profile of the Sharps Bros ultralite handguard series. I do not know if the BCM will fit the SBUR03. To be safe, get the SBUR04.
The Strike Industries Gridlock handguard will work with some Billet Upper Receivers. So that handguard might work with the Sharps Bros. Upper Receiver Ar-15 Billet W/dust Cover but fitment cannot be guraranteed.
Yes you can now find the SBUR04 upper on optics planet as well.

The rear facing tabs on the Mk4 handguard would likely interfere with this SBUR03 model. The Sharps Bros SBUR04 upper will fit the MK4 just fine.
Yes, the Sharps Bros. Upper Receiver Ar-15 Billet W/dust Cover should work fine with the Noveske NHR Rail.
This is a billet upper receiver and is compatible with any standard AR-15 lower receiver including all mil-spec options and Sharps lowers. If you have a billet lower receiver, perfect fitment cannot be guaranteed as billet receivers by different manufacturers can have slight variances in tolerances.
