All Trilogy Autocockers come with a non-adjustable low pressure regulator. Its the low pressure regulator that controls how hard the gun recocks. The harder the gun recocks, the more likely you're bolt will be to chop a ball. The Low Pressure Nut allows to you install any aftermarket low pressure regulator on to your Trilogy. In turn, you can lower your recocking pressure to the point were the bolt will actually stop on the ball rather than chop it. This is a great upgrade for Trilogy owners looking to get the most out of their marker.
