I recently built my first AR and am very happy with my setup, except for one thing. I haven't been able to get my sling setup quite right. Everything works well, but I'd like to tweak it to get it perfect. Please pardon my long post, but I believe in providing all the details up front when asking for advice.
All my components are high quality parts, but they're just not working together well for me.
The sling itself is a Viking Tactics wide padded model, which I'm very pleased with. The sling isn't the problem.
Up front, I have a few KeyMod QD rotation limited sling mounts on my KMR. Again, these are great and not part of the problem. These are great pieces of kit.
The problem is in back.
The buttstock is a VLTOR IMOD Clubfoot. For the most part, it's a good stock. I really like the clubfoot feature for prone shooting. However, the lack of rotation limiting on the QD socket ruins the whole deal.
The sling gets twisted around easily. It's a minor discomfort, but one that's fixable. I don't want to add zip ties to hold the swivel or otherwise defeat the QD feature.The heavy duty QD swivels work well and won't come out of the mounts no matter how hard I pull or fling the rifle.
I tried to fix the problem by replacing the VLTOR endplate with an IWC endplate with a rotation limited QD socket. This also seems to be a good piece of kit.
The rotation limiting works very well and makes for a good attachment point, but when the buttstock is completely retracted, it bumps up against the button of the QD swivel. This hasn't caused the swivel to release so far, but I can see it happening at an inopportune moment.

So, the solution.
The best solution I can find for the buttstock is to simply replace it with a B5 SOPMOD Enhanced model. Newer models have limited rotation for the QD socket.
I know the BCM buttstock will have QD, but it will weigh considerably less. I have a stainless BCM SS410 16" with a 13" KMR, so I'm concerned that this might upset the very nice balance I have now.
Not sure what to do about the endplate. I don't know if the B5 will bump the QD button. Not sure if the problem is the endplate, swivel or the buttstock. Any suggestions would be appreciated. Thanks for reading all my BS.
