While attempting to get my gas tube aligned before installing the pin my gas tube has become stuck in my gas block. I am using a Superlative Arms adjustable gas block and the supplied gas tube that came with the barrel from Craddock Precision. I don't want to use plyers and risk damaging the gas tube. I have looked online for a gas tube wrench like this one https://www.brownells.com/tools-cle...ols/wrenches/ar-15m16-308-ar-gas-tube-wrench/ but they are all listed as either sold out or discontinued everywhere I look. Does anyone have another tool they can suggest to remove a stuck gas tube without damaging it?
