Tried 2, neither fit

Purchased for use on a VooDoo 16" barrel. Barrel measures .749. First gas block I received measured out at .743. Contacted Brownells and their amazing customer service sent me a replacement. I finally got time to try it and the new one would not go on either. New one measures out at .745. Tried heating the block and freezing the barrel and still could not get it on. Google search turned up that I'm not the only one that has this issue with them. Purchased another brand and it installed with no issues at all.
