The buffer tube and butt stock can be used on an AR10, the buffer weight and spring are made for an AR15 and will need to be swapped out with the correct buffer weight and spring.
Yes, the Hogue AR-15/M16 OverMold Collapsible Buttstock Assembly will be compatible with the Mini EXCL Lite. However, I would just recommend purchasing the stock by itself as your rifle does not need a buffer and spring. You also wouldn't need a new buffer tube. You can simply replace the existing stock on your rifle with the Hogue AR-15/M16 OverMold Collapsible Buttstock, which can be found by using the link below:

This item comes with the buttstock, buffer tube, castle nut/lock plate, buffer spring, and buffer.
It will attach to a Mil-Spec buffer tube, as well as includes a Mil-Spec buffer tube.
Unfortunately, Hogue does not provide specifics regarding the included Mil-Spec buffer tube and spring material. I suggest reaching out to the manufacturer directly and requesting more information.
