Magazine tube spring

The 60 inch spring is recommended for use in the longer dedicated 12 shot or more extensions.

These springs can be trimmed to reduce the amount of force required to insert cartridges into the magazine however it is recommended that they initially be used in their full length as they will take a set thereby reducing their overall length. Trim in small amounts. A spring that is too short will not eject the last few cartridges efficiently out of the magazine resulting in failure.
