Review on Manson Precision 5 56Mm Headspace Gauge by Cameron Aleman

I have completed my first build, this time with an Aero Precision barrel and action. They were supposed to be in perfect condition but I bought them anyway to double check. Go to the pressure gauge, the shutter is closed. No movement, the shutters did not close. Light. Test shot and the gun ran like a champion. It's a small price to pay to make sure the gun doesn't shoot you in the face. The gauges were well labeled and easy to read. Good to know I have them for future builds.
