Single RMS mount for XR15 and XR30, interchangable?

[125mph]

If I get an RMS mount for the XR15 (single arm style), can I use it for the XR30 if I have the spider slide thing that fits the XR30? This thing?

Yes this should work as long as the RMS track is long enough for where you want it placed. There is no difference in the RMS track for either of the light mount track slides. On one of my large systems that is a peninsula I have three XR 30s and one XR 15 mounted on the same track going from end to end using the RMS Multi Light mounting kit and a 60.5’’ Multi-Light RMS Track. Works great!
