So I have several Midwest Industries AR free float tubes with a provided QD rail section. One them, If I rotate the QD sling attachment they fall out.

I looked into it and the ring is not completed always around them.

Then I went and looked at my XLR Chassis which has a QD socket. In it, there is a ring run completely around the inside of the socket.

SO then I started tuggin on the XLR chassis. and the freaking QD attachment pulls out of the socket.

Two questions.
1. Do all QD attachments all pull out if tugged hard enough?

2. Or do I need to purchase a different brand of QD sling attachments?

The QD sling attachments I have are some off brand no name I got for free....should I go the distance and get a Magpul?

I think Midwest uses a "limited rotation" qd socket, and have found that some inserts work better than others in mine.
I've even noticed that while 3 out of the 4 Magpul studs work quite well, that 4th one will just not stay in no matter how hard I try.

No.

Sounds like that's your culprit. Probably cheap Chinese airsoft crap, made to look like the real deal without actually performing like it.

These have been working out really well for me also . They are strong, silent, they don't twist my slings up, and they are easy on and are easy off, but only when you want them to be. I have the front sling attachment on my Hodge upper going through a Wilson Combat QD swivel rail attachment. It adds a little weight, but it keeps the Blueforce Gear cable loop away from the hot barrel, the rifle hangs better at my side (no flop over) , does not abrade the cable like going through the rail slots or holes can, and I can put it exactly where *I* want it. The rear cable loop is attached through a rotating detachable eyelet installed into the Magpul SL stock's QD socket (it can rotate, but it doesn't tangle). As for slings, I prefer the Magpul MS1 series slings, their strong, long lasting and soft webbing material, comfortable, and they are easy and quick to adjust, they hold adjustment and they are low profile ( nothing hanging or dangling). The way I have the U-loops setup on my rifle, they move freely and don't tangle or twist my sling. One can also use the elastic covers that are sometimes used over H&K snap hooks over your U-loops , if you feel the need to. Have been using them for a while now, and IMHO it would be close to impossible for them to come loose on their own. Below is a link to a review of the BFG U-Loop. I have also noticed that the Proctor sling is now offered with QD swivels. I wonder why ?

Sounds like the sling QD is cheaply made. I'd get a new sling or QD.

I got some Magpul QD sling attatchments and they made the difference.

They work in the two MI free float tubes and on the XLR chassis I have....

goes to show, you get what you pay for.
