Opposite problem than most - Strike Industries .223/5.56 Enhanced Ultimate Dust Cover

So first ill say is the material is good, it fit on multiple uppers for me with no issues as you will find in other reviews. My issue is that the spring mechanism to pop it open doesnt seem to be functioning. It will open when charged but no tension or catch points to make it spring open like it should. All in all it functions as a dust cover when storing the rifle or moving about. But if you want it to pop open odds are you may get a qc dud like mine or even others having other clear qc issues. Based on other reviews i wont even reach out to manufacturer as no response seems to be the common trend.
