clamp on design means no roll pin drama if you ever swap barrels. dialed in on a 14.5 mid length, took about 14 clicks from full open to lock back elimination. clamp screws stayed put under sustained fire
Superlative Arms adjustable .750 clamp on melonite gas block is a real quality of life upgrade over a fixed block. Clamp on means no dimple required. Adjustment screw lets me tune gas precisely. Melonite finish handles heat.
