You guys are wasting your time and product cleaning the gas tube. Do you think with all the pressure that there is really going to be anything left in the tube that really needs to be cleaned out?
I field strip mine at around 400 or so rounds. I actually ran 1,200 rounds before I field striped it the first time. I wanted to see how many rounds fired before it started malfunctioning. The BCG and upper receiver where caked in carbon.
How often does everyone clean the gas tube on their AR's?
