You can buy a solid, non-collectable USGI replacement stock anywhere (Fleabay, GunBroker, WTS forums, gunshows, etc.) for about $30-$50
That sounds a bit low for a solid USGI replacement. I got a good walnut SA at What-a-Country for $55 about 5 years ago, but they had "c" tip slings for $45 then, too. - Bob
