I have a slightly used ACE Skeleton stock, the short version. Including CAR buffer and spring and all mounting hardware.
Only problems are it's missing the foam sleeve for the tube, and there's a scratch on the tube, and there's some mounting wear on the end where you can slip a stock wrench on to tighten it.
I won't refuse any reasonable and intelligent offers on this, as I understand the prices fluctuate a lot between retailers and Ebay. So make an offer of some sort, just trying to get rid of the gear box clutter.
