Does anyone have a source for a rotating sling swivel post, threaded 10-32, that could be used on the mid mounting point on this stock. YHM makes one for their free float tube, but is a non standard thread.

ACE sells one. I have one, but I haven't used it yet. I would prefer a better way to attach a sling to the side of the stock. Check it out at www.aceltdusa.com/accessories.htm. They sell direct.

Thanks for that help. From the picture on the ACE website, it doesn't appear that it rotates though. The allen head mounting screw seems like it would bear against the post body and would lock it down when tightened unless there is some bearing arrangement that isn't visible. Plus it looks like you are stuck using the supplied wire GI type swivel loop, as opposed to a quick release "Uncle Mike's" type which requires a different mounting post.

Ace came out with one not too long ago, don't know if it is in their catalog but it is on their website. Standard Milspec swivel and rotates. Works great on the mid-mount position.
