Anybody knows which buffer tube, buffer and buffer spring if using the ACE Skeleton Aluminum buttstock ARFX on a DPMS LR308?

this:

Rifle length tube, rifle buffer, and Armalite uses the same spring for Rifles and Carbines. That will be all you need.

I got my. 308 rifle buffer and spring from midway, under 35$ shipped.
That and the A2 buffer tube is all you need with the ace stock piece.
If you have the extra funds I would recommend buying from heavybuffer, I have one in my 21" and it really reduced felt recoil. It may not be a need to have but it sure is a nice to have.
That and the ace kit. Maybe a screw if the kit doesn't have it.
