Gunsmithing Sws barrel nut.

Call novekse and see if the newer NSR nuts will work. I have used both and i remember them being pretty close dimensionally speaking. i did not mic them up tho, so apply salt liberally.
 
where is it interfering? ill have to put this info away in my notes in case my SWS nut is unusable
The holes are a certain distance from the face of the receiver.... the handguard holes are not the same distance from the receiver. The distance of the holes from each other is the same, however the handguard hits the receiver before lining up with the holes in the barrel nut.

Was SMOS the OEM for that rail? It'r probably a long shot, but they may have a nut that will work. I think their OEM/machine shop side is just "Stubborn Mule" these days.

No sws made them and has no more of the old nuts available. I don’t think they are in business anymore at all. The barrel nut had a proprietary wrench you had to use to get it on and off too, stupid I know
 
This is the barrel nut you will be needing, also they use a certain wrench and they’re super hard to come by it seems.
