Mine has no defects and works as expected with magpul and fab defense qd mounts - Armaspec QD End Plate

ODG color is very close match to other ODG parts from Magpul and AT3.
Fit and finish is great.
The threaded port for installing and removing the takedown spring and detent is great, though may need a little locktite to ensure does not come loose during extended use.
QD slot holds the weight of the rifle and then some using either a Magpul or Fab Defense QD mount post.
Very tight fitting into the receiver, but that receiver was Cerakoted so that probably made things a little more snug than regular anodized receiver, but I actually like a snug fit anyway, so would definitely buy and use again in Cerakoted reciever.
Good price though a little more cost than the Rainier Arms QD endplates (which are completely sold out until 2027). This makes a great second choice when the Rainier Arms QD endplates are unavailable.
