I received my 24" Sabre Defence Grendel barrel and I have a .936" PRI gas block. The issue I am having is that the SD barrel has no index flats for the gas block set screws. I am worried about aligning the gas port in the bbl with that on the block. Anyone care to share their expertise in installing as gas block in this situation?
