I have a complete XR15 G3 pro with rms mount (short slide only) I do not have the original screws to the rms mount but it will have 4 bolts to be able to properly secure the light to the mount and diffuser included as a full package as pictured below. $325 shipped to CONUS. Not sure of manufacturing date upgraded to xr30 g3 pro and this has been sitting was used for about 2.5 months and ran smoothly with no issues at all, And any questions feel free to pm me.
