Design has known flaws - Primary Weapons Systems MK111 MOD2-M, .223 Wylde, 11.85 in Upper Receiver

At about 1500 round Mark I started noticing issues. The accuracy was terrible and the interior finishing was coming away. B they have many rifles and I’m able to shoot from one to 3MOA with reference ammo. This thing was shooting above 6MOA, sometimes struggling hit a 10 inch plate 200 yards. I did a deep clean and found that the camp pin was gouging part of the inner receiver away. I sent it back to PWS. They responded that gouging of the receiver by the campaign is a known problem and their engineering team is working to solve that with the next generation. He also claimed to have shot a one MOA group, which I absolutely do not believe.
