This one works Well!
At first I purchased the Troy Professional Grade Rifle Receiver Sling Adapter. Could not collapse my stock with that one.
This Troy OEM M4 Sling Mount Sling mount is built right and as low profile as possible for an ambidextrous mount.
I Highly recommend.
Troy does make very nice equipment, could be less expensive as with much of their merch. Very easy to install if you are mechanically inclined. Careful not to lose your takedown detent spring during installation.
Will work with both single point and two point slings, Makes no noise like the Magpul ring that flops back and forth and gets stuck in your collapsible stock.
Get the Troy.
Pros: Ambidextrous
Cons: Price
