Marlin 60 Ejector Spring - Nickel Gauge

This is the Nickel Gauge, an ejector spring gauge for the Marlin 60.

If you own a Marlin 60, this is how to tune or check the ejector spring for proper position without calipers. It just so happens that a Nickel is close enough in thickness to use to measure maximum ejector spring height and proper ejector spring side position on a Marlin 60.

You will need to remove the trigger assembly from the receiver to properly insert the ejector spring gauge into your Marlin. Check out out Marlin 60 Disassembly Video!

You can use a Nickel or Penney to measure with. The Nickel is a high limit .075 gauge and a Penney is a low-limit .060 gauge. Anything in-between is a good position.
"Nickel high & Nickel wide" is a good way to remember.

Place a Nickel on top of the feed-throat. Flush top of the spring to top of the Nickel.

Push down the Lifter and place the Nickel on the inside of the feed-throat holding it straight up. Flush face of Nickel to side of spring.
