Ive used at least 4 adjustable gas blocks, most really cheap Chinese ones and have never had a blockage and one of these rifles is a 7.62x39 I built with many thousands of rounds of cheap steel cases ammo though it. I have never had to adjust them after set though, does this only affect adjustments or are yall saying they will clog up and cause malfunctions?
