Geissele Super .750 low profile gas block has slightly different black finish than my other Geissele parts in direct light. Mechanically perfect, set screws engage cleanly. Function is exactly what you need. Cosmetic only variation.

Geissele Super .750 low profile gas block is well machined but install required care to clock it properly with the gas tube. Took two tries to get the rotation right before tightening. Once installed it stays put. Quality steel construction.
