Brand new 12GA to 22 MAGNUM Shotgun Adapter Designed for break-open shotguns Precision machined from stainless steel made in the USA This adapter has a SMOOTH BORE This adapter gives your 12 Gauge single or double shot break open shotgun the ability to fire a 22Magnum 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 22 Magnum 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 smooth bore is gently reamed through the adapter for the bullet (no 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 Carry one gun and have the ability to shoot not only 12GA shells but also 22 Magnum bullets Surprisingly accurate! Not recommended for pump action or semi-auto shotguns. Designed for use with break open style shotguns. This chamber / caliber reducer will NOT work with 22LR/22 long/22 short ammunition.
