If your port is too large, and you choke it with a turned down adjustable gas block, the port becomes subject to more torch effect, leading to early port erosion and accuracy degrading.
When I get a chance Ill pull the gas block again and see what it measures. I had this barrel custom profiled after I bought the DPMS lo pro gas block that is on it. So I had him leave the gas block journal the length of the DPMS gas block, so it would be best to stick with it anyway as I would have to have the gas block journal turned down to match the length of whatever block I was using and in that case I might as well go to a .750 Gas block and journal so it would fit.
