So far so good
This gas block went on a large frame gas gun in 308 that has a .936 diameter barrel from Craddock Precision. Initially I had an adjustable gas block from another prominent company that ended up failing and breaking - so I figured why not go with one of the best. I aligned the gas block using a borescope to make sure that the port is perfectly aligned. I went to the range with the gas completely shut off and increased until I had bolt hold open on last round. So far, this gb has performed flawlessly. We shall see how it holds up after several matches.
