MX Drop Out Stock W/Recoil Reducer

Bought this stock on this site to put on my MX15 -ended up selling gun and am going to another type of gun.
Previous owner used it on a DB81/MX10

It has a recoil reducer -I think an earlier version Rad, but not sure, but seems to work fine by previous owner. I had a new recoil pad from an estate sale I thru on it. Needs to be ground and fitted. Overall, it came to me in used condition, but still a lot of use in it.

Price to sell @ $325 shipped
