YHM .750 low profile gas block has slightly different black finish than my other YHM parts in direct light. Mechanically perfect, set screws engage cleanly into the dimple. Function is exactly what you need from a gas block.
YHM .750 low profile gas block is well made steel but install required care to clock it properly with the gas tube before tightening. Took some adjustment. Once locked in it doesnt move. Set screws engage cleanly into the dimple.
