This item consists of 6 used Romanian AKM wood buttstocks. 5 of these have holes drilled in them, and I have no idea what the holes are for.
I would guess it would be fore a scope mount, or optic mount of some kind. Maybe a flashlight mount. One of these has some wood cut out, not sure why.
Sold as is. It would be cool to know what was mounted, and more cool to have some of those and put them together as a package.
