Marlin 60, 22lr Part. Magazine Tube Band, and Recoil Spring Guide w/Spring MARLIN Model 88 USED 22 L.R. Outside Magazine Tube W/Butt Plate. The outside surface of the Marlin 60's magazine tube is flat, while the inside has a slightly curved surface. This allows for easier loading from the top, and provides space for additional spring steel inside the tube to absorb shock when the gun is discharged. In order to load the magazine of the Marlin Model 88 we need to remove two screws that hold the ejector rod assembly in place. Then lift out the rod assembly to reveal a small hole directly under the trigger guard. Insert a pencil or similar object through this hole and push it all the way down into the gun. It will contact something solid if the gun is loaded properly. Remove the object and repeat with another object. If you insert too far up into the hole, it won't go all the way into the gun. Not enough pressure will be applied to the pencil lead to cause it to shoot out of the end of the barrel! Load one more cartridge into the chamber and press the button on the side of the handle to release the charging latch. The round will enter the chamber, go through the ejector rod, and out the other side of the barrel.
