One of the downside to the Crickets that you hear all the time is how cumbersome it is to switch magaizines. Most of the time you need two hands to complete a simple task. This modified side plate allows you to do just that, pull back the indexer and rest it in the second slot. Once the magazine has been inserted, lift up the indexer lever and return it to the front.
*Not compatible with .357 Cricket
Please note* Do not tighten the right screw too tight. This will lock the index arm. See pictures.
