So, how do you transition a MS3 to single point and attach at the stock / frame joint? The adaptors I see have a sliding ring for the clip end, so how do you attach the quick release swivel end to the D ring in the sling???

They make 2 different versions of the MS3 a QD and snap-hook. Sounds like you have the QD version trying to connect to the D-ring attachment which is meant for the snap-hook version.

Snap-hook MS3


QD MS3


This is the Type of end plate that is usually used for connecting the QD sling to the back of the receiver.

Thanks, ordered the end plate.

Midwest Industries, Troy, and Tango Down all make QD end plate adapters that can be installed without removing the castle nut and factory staking. I prefer Midwest Industries. If your castle nut isn't staked I would recommend installing a QD end plate. If it's staked then go with an adapter.

As does Daniel Defense, GG&G, and Tactical Link.   I know because I recently spent way too much time looking at them all...and finally decided that the Tactical Link Z-360 was the best for me:

Yeah, the price is ridiculous...and so is the price for the Tango Down.  The others can all be had for close to $40.  Links to the others:

Troy Industries Professional Grade Rifle Receiver Sling Adapter
Tango Down PR-4 Rear Sling Mount


With the exception of the GG&G, all six are ambidextrous, but most of them are ambidextrous because they have a connector on both sides of the collar.  That helps left-handed people, but you aren't going to move the QD connection just to temporarily switch your rifle to your other shoulder, so I think that it's a stretch to call them ambidextrous.  In my opinion, you need a rear-facing mount to be "tactically ambidextrous".   Of course, you can definitely make the others work in a tactical situation, but the transition will not likely be as smooth.

Of the six options, only the Tactical Link and Tango Down have a rear facing QD mount (Tango Down also has two side mounts).  I vastly prefer this design, which not only allows true "tactically ambidextrous" use, but also helps protect the QD release button. You are far less likely to trigger the QD release on your sling with a rear-facing mount.  With a side-facing mount, the release is always bumping against your chest, tactical vest, or other gear.  Sooner or later, that release is getting triggered...and probably at a bad time.

The reason that I preferred the Tactical Link over the Tango Down (other than price) is primarily because the angle of the Z-360's connection point is about 45 degrees downward.  The Tango Down's rear-facing mount faces directly back, much like the well-regarded Noveske that sits between the castle nut and the receiver.  The downward angle seems to help the swivel, but more importantly, it protects the sling's QD release from being triggered if you inadvertently collapse your stock fully.  The Tactical Link's connection point is also made from stainless steel and should stand up to quite a bit of use/abuse.  Bonus points - the Z-360 collar comes in a wide range of colors, which you can preview on Amazon.  Most of the others only come in black...and their black often looks grey.  BTW, while you can preview the available Z-360 colors on Amazon, it is less expensive on the Tactical Link website right now.

Regardless of which one you choose, if you go this route you will no longer be able to fully collapse your stock.  Whether or not that is an issue is personal preference.  Do you use your AR with the stock fully collapsed (perhaps when wearing gear) or do you just collapse for storage/transport?  Also, do you have a six-position buffer tube?  If so, losing one position is probably not a big deal.

This is where someone says just unstake your castle nut.
