Lightweight and slender, but qd mounts don't work. - Aero Precision M5 ATLAS S-ONE M-LOK Handguard

When I was shopping for AR10 handguards, I had three goals for it. It had to be as lightweight as practical (full top rail was not necessary). It had to match the .210 tang on the upper receiver (my upper is also from Aero Precision). Lastly, I wanted magpul qd sling mount compatibility. Two of these things are as just as I wanted, but the third is not. The qd sockets are the correct diameter, so you can insert the sling swivel into it. However, you're unable to push it in far enough to engage the lock on the sling swivel. Maybe this can work if ya use a smaller barrel profile, mine is a Faxon Big Gunner 308. But the Big Gunner profile barrels are already pretty small. I don't know, just be careful. I'll still use this because it looks good and I can just buy an m-lok qd socket, but I'm just kinda bummed it didn't work out as perfectly as I imagined.
