The Diameter of the gas block is .875.
Whoever claimed the gas block diameter is .750, YOU’RE WRONG. Based on your answer I order a .750 gas block only to realize during my build that it’s .875 - totally putting my build on pause until the correct size block arrives. Don’t give an answer unless you’re 100% positive it’s right. For the record - the gas block size is .875.
The gas block is definitely. 875" and the gas tube is rifle length. Ben, you need to stop giving the wrong answer, no answer is always better than the wrong answer.
