First disappointment from optics planet - Kexuan High Profile AR-15 Railed Gas Block

This is the second Kexuan railed gas block I have bought- the first actually was bought on Wish, and actually worked great; the hole for the gas tube was right, ported correctly and held securely on my barrel. So I expected the one from Optics Planet to be just as good, if not better. Unfortunately, the hole for the gas tube is too large, and when I tried putting the gas tube in it rattled around- so obviously it would just allow most of the gas to exit AROUND the tube, rather than through it, to cycle the bolt. Basically the only thing this gas block is good for is a paperweight. But at least it was cheap, so I’m not too mad about the wasted money.
