Has anybody used this AR Stoner adjustable gas block from Midway USA? It looks like it could be a solution to the adjusting screw backing out. Which how common is that anyways? Is this gas block a solution to a problem that doesn't exist? I want to do an adjustable block on a sometimes suppessed sometimes not AR.
