12GA RIFLED BORE ADAPTOR 2.45"

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 smooth bore is gently reamed through the adapter for the bullet  (no rifling).
