Either won't stay closed or won't open easily - Strike Industries Billet Ultimate Dust Cover

The product is a good idea for a quickly attached or removed dust cover that is quieter than most, but a bad design. The weak spot is the spring ball bearing that is supposed to keep the dust cover closed. Also not super useful in terms of being "silent" because the charging handle and bolt moving will make just as much noise as a dust cover flipping open, and you can add a little rubber pad to a regular dust cover to do the same thing this one does. How often do you remove and install your dust cover that you need it to be quick detach anyway?
