J's Review of Maxim Defense Industries PDX U.R.G. Mil-Spec Upper Receiver
There is an issue with cycling 223 cartridge to the 556 upper receiver. I was able to isolate the cause. I sent it for repair in maxim defense, but after they replaced the barrel, gasblock, the issue is still there. The last reply they gave me are as follows. So it seems that this is a universal issue with their upper. With this price range, it seems ridiculous that it will only run 556 ammo. Other upper that are way cheaper don't have this issue.
The PDX 5.56 is built and tuned for 5.56.
.223 is not recommended, it is too soft of a load and may not run well.
