Wilson Combats low profile .750 gas block does the job, set screws tighten down into the dimple correctly. Black phosphate has slight tone variation across the surface, only noticeable in side by side. Sits low enough to fit under a tight handguard. Performance is correct on a 16 inch carbine.
Wilson Combats lo-profile gas block at .750 dimensions is what most standard barrels use. Set screws have the proper engagement angle to bite into a dimpled barrel. Black phosphate finish. Fits under any standard free float handguard with room to spare for the gas tube.
Wilson Combat .750 low profile gas block works correctly but at this price you can get a Geissele or Aero block that performs identically. Set screws engage cleanly. Steel construction. The Wilson name premium is real, the performance is standard.
Wilson Combats .750 low profile gas block is well machined steel with proper black phosphate finish. The set screws thread cleanly into the body and bite into a dimpled barrel correctly. Lower profile than a standard milspec block means it fits under tight handguards.
