SIDEKICK CHAMBER INSERTS - Three gauge set with tools and case.

SideKick drop-in chamber inserts are designed to fit most 12 ga. o/u or s/s shotguns with 2-3/4" chambers without any barrel alterations. Some shotguns may require an inertia trigger conversion to reset the trigger for the second shot with the 410 bore only. Each set has an integral extractor that ejects or extracts with your gun. Each set comes with complete instructions and tools to insert and remove the inserts. Available in individual gauges or as a complete set. Please specify the make and model shotgun in the comments section of your order.
