12GA to 20GA - Shotgun Adapter

Precision machined from  stainless steel

Proudly made in the USA

This adapter gives your 12 Gauge single or double shot  break open shotgun the ability to fire 20GA ammunition.  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 20GA 2 3/4" ammunition.  After firing simply remove the  adapter and tip upside down to remove the spent shell.  A smooth bore is gently bored through the adapter.  The 20GA 2 3/4" cartridge side is precision CNC machined to the exact  chamber dimensions to accept 20GA 2 3/4" ammunition (SAAMI chamber specifications).  This adapter is not machined to fire 20GA ammunition that is longer than 2 3/4 inches.

Every adapter is laser engraved for easy caliber conversion identification.

Adapter orientation is not important and the adapter will  work in any position.
