Mag swivel mounts and qr swivel attachment - Magpul Industries M-LOK QD Sling Mount

I purchased both these magpul mounts AND the QR swivel attachments and they are very good quality….BUT I then went on Amazon and purchase very similar products for FAR LESS. These MAGPUL have a flat-gray finish and the BENGOR brand on Amazon are shinier and black, ……but aside from that, the BENGOR QR / mounts and swivels operate the exact same way…..with either fixed (1/4 turn) or 360* turn…..I buy plenty of MAGPUL products, but IMP they seriously overcharge for these particular items.
