20GA RIFLED BORE ADAPTOR 3"

This adapter gives your 20 Gauge single or double shot break open shotgun the ability to fire a  bullet.  This adapter is  precision machined from high quality stainless steel to the OD specifications of  a 2 3/4 20GA shell.   After firing simply remove the  adapter and tip upside down to remove the spent  shell. A smooth bore is gently reamed through the adapter for the bullet  (no rifling).
