See, I am going to have to disagree there tahunua001. I will put my Hk against any DI gun for reliability. I promise eight out of ten times you will have to clean yours first. As far as specific pressures, the Hk has a self regulating gas block. It has never failed to fire any round, including low powder sub sonic loads or any hand load I have used. While reliability may be an issue for some piston manufactures or piston conversions, an LWRC or Hk are very reliable, I will even say more so under certain conditions.
