2. Over-sized Gas Cylinder
« on: October 20, 2012, 12:44:57 AM »
 The gas cylinder on your M1 Garand is a consumable item. When the gas piston moves back and forth in the gas cylinder the diameter of the gas cylinder will slowly increase from wear. As the gas cylinder increases in diameter more pressure is lost during the gas cycle. To properly measure the inside of the gas cylinder a gage is required. The most accurate and economical method is to use two gage pins.
