556 upper receiver won't cycle the 223 cartridge.
Written on Oct 14, 2024
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.

Flickering

Looks like I got a used or old item. I just discovered it has some issue when you just tap at the bottom area. The result is, sometimes the dot will flicker and turn off when I just dry fire or pull the trigger. This is useless and there's no option to return. Very disappointed, just a waste of money.
Very difficult to adjust and won't hold zero

It's very troublesome to adjust and once you tighten the set screw as instructed, it still wiggles unless you maximize the windage to left but then if you do that, the adjustment is way off.
