I did a search and didn’t find anything on this so here goes: what front sling mount (rail mounted) would work with a Magpul MS2 sling (other than the RSA which seems to be vaporware)?

I’ve never used this but it looks like it got a couple good reviews. Hopefully they will actually release the RSA soon.
Here is another thread they discuss the same thing.
Thanks, M4gery! My search skills must be lacking.
Be prepared to do a bit of shaving to get a better range of motion, it is limited to two positions, laying flat or a 90 degree angle, it will not freely switch between the two. Well, mine will not. You may prefer that.
I vote for the RSA. 
Yes, given that I’m not very good with tools, I think I’ll just use the MS2 as a single-point sling until the RSA come out! :laugh: Thanks, everyone.
It would be nice if the MS3 had options as to what you wanted on the “2nd point”, where the lockjaw currently sits. However, I guess a QD on that end would defeat the purpose of being able to switch from one to the other quickly.
Might Stick be eluding to an imminent release?
I have three rifles waiting for an RSA, but if I needed an immediate option, it would be a used DD offset ring mount or a LUSA.
You can backorder from Brownells
They appear to think release is imminent. YMMV
