Board policy mandates I state that I shoot for BCM. I have also done work for 200 or so manufacturers within the firearm community. I am prior service, a full time LEO, firearm instructor, armorer, TL, martial arts instructor, and all around good guy.
I also shoot and write for various publications. Let me know if you know cool secrets or have toys worthy of an article...

I think their good fit is as simple as this, “Slide the handguard onto the barrel nut. Be very careful when doing this as the clearance between the OD of the barrel nut and ID of the handguard is precisely machined to about 0.001” clearance.”
The rail should slide on with some light taps from a rubber mallet or piece of wood.
I do not put any grease on any outer barrel nut surface that uses a slip over rail as this grease lowers the friction between the ID of the rail and barrel nut, which causes the rail to squirm, causing zero shift issues.

I read what I believe is something that someone posted in a large post on this site, regarding Geissele having tolerance issues with certain rail models.
I'd love to see a link.

I assumed that the OP was referencing this thread, which seemed to mostly concern the MK16.

On page three and four comments are made about barrel nuts.
