High quality part and really is a noticeable upgrade - Strike Industries Multi-Function End Plate and Anti-Rotation Castle Nut

I was impressed with the quality of this end plate and especially the castle nut. The finish on the castle nut is superb and the metal is hard enough that it didn't wear the anodizing off when torquing it down. Visually, is nice without having to stake the castle nut since it has the screw that fits in the notch of the castle nut to keep it from loosening. Also a very functional added plus that my single point sling now readily attaches to my AR pistol. I plan to purchase again for my next AR pistol build.
