Hello,
No we don't but it wasn't for lack of trying. The magwell on the 595 was too small for any common mag to go into. I think the action itself was too wide as well, since it's a flat bottom. Then there was the recoil "lug" issue. Great actions but unfortunately it just didn't work and of course they don't make them anymore and there's really not that many out there. Sorry for the bad news. If you are really lucky you may be able to find a Master Sporter stock which is just about the pinnacle of ergonomics (that fit me personally).
