The Shooter’s Box 12 gauge to 22lr Rifled adapter

This adapter gives your 12 Gauge single or double shot break open shotgun the ability to fire a 22lr bullet. This adapter is  precision machined from high quality stainless steel to the OD specifications of a 2 3/4 12GA shell.  It will easily fit into your break open shotgun barrel and accept any 22LR or 22 Short ammunition.  After firing simply remove the adapter and tip upside down to remove the spent 22 shell, or use your finger nail to grab and remove the shell while the adapter stays in your gun.  The  wide groove cut in the face will not only allow you to easily remove a spent shell but also provides a recessed clearance area for your firing pin.   Adapters that don't have this recessed area (or recessed area in the wrong spot)  do not provide the proper clearance for your firing pin and may damage your shotgun.  A rifled bore is cut through the adapter for the bullet (push rifling).

Adapter orientation is not important and the adapter will work in any position. 
Will fit any break open shotgun with 2 3/4" or 3" chambers.
Perfect for 'Preppers' or your Bug Out Bags.  Carry one gun and have the ability to shoot not only 12GA shells but also 22LR / 22  Short bullets.
Not recommended for pump action or semi-auto shotguns.  Designed for use with break-open shotguns.

This chamber / caliber reducer will not work with 22 magnum ammunition.
