Qd points are useless. - Aero Precision M5 20in .308 CMV Complete Upper Receiver w/ Flash Hider & ATLAS S-ONE Handguard

The QD points in the handguard can't be used because the barrel is in the way and they can't be inserted. I know in the grand scheme of things this is fairly minor but really? This is your own proprietary rail on your own proprietary upper and the integrated QD sockets don't work. I'm not even using some random off brand QD swivels, they're Magpul QD swivels. You know, the brand of accessory that's installed on MOST OF YOUR RIFLES.

The fit and finish is great and it fits perfectly with an Aero lower so I can't trash it too hard. Otherwise solid.
