Narrative:

IFR route filed and clearance received was kprc drk V105 fmg V165 maver kuao. Approximately 10 miles northwest of las; approach control asked me if I could accept direct fmg direct destination. I responded affirmative and was given said clearance. Shortly after I was handed off to nellis control. While reviewing my projected flight path I realized that at my altitude (16;000 MSL) this path would pass through one of the restricted airspaces: either R-4810 or R-4812. I called nellis control; identified this situation and asked if this would create a problem. I was told it was a problem and that I should be on my cleared route on V105. I informed nellis that las vegas approach had cleared me direct fmg; but [I] accepted nellis' direction; informed them that I would intercept V105 and continue on the original clearance. I don't know if the modified clearance given by las vegas approach was improper; or if the modified clearance was not provided to nellis [control]. I do know that following the modified clearance at that altitude I would have entered the restricted airspace.

Narrative: IFR route filed and clearance received was KPRC DRK V105 FMG V165 MAVER KUAO. Approximately 10 miles NW of LAS; Approach Control asked me if I could accept DIRECT FMG DIRECT destination. I responded affirmative and was given said clearance. Shortly after I was handed off to Nellis Control. While reviewing my projected flight path I realized that at my altitude (16;000 MSL) this path would pass through one of the restricted airspaces: either R-4810 or R-4812. I called Nellis Control; identified this situation and asked if this would create a problem. I was told it was a problem and that I should be on my cleared route on V105. I informed Nellis that Las Vegas Approach had cleared me direct FMG; but [I] accepted Nellis' direction; informed them that I would intercept V105 and continue on the original clearance. I don't know if the modified clearance given by Las Vegas Approach was improper; or if the modified clearance was not provided to Nellis [Control]. I do know that following the modified clearance at that altitude I would have entered the restricted airspace.
