Angel LCD Pressure Gauge Adapter Internal Marker Upgrades simply putThis accessory replaces the LPR end cap at the front of the Angel with a tiny micro gauge which constantly monitors the LPR pressure of the marker. The gauge can be left on the gun at all times, and measures just 1. 2cm (half an inch) across. There is a clear 6 bar (87psi) indicator which tells you where the dial should point for the recommended LPR setting. The LPR pressure gauge adapter is designed to fit all Angel LCD markers.
