Gas tube blocked - Tiger Rock .750 Low Profile Micro Gas Block and Sliver Rifle Length Gas Tube, Assembled (GTRB, GB01-B)

Glad I checked flow before installing and ruining a range day. It come preassembled, so I test air through the tube. And no air was passing through. Tried to blow it out with a compressor, no luck. Took the tube off the gas block, tested air, and nothing. Giving it 2 stars because the gas block fit nicely on my ballistic advantage barrel. Unfortunately had to use my old gas tube on a new build…
