12GA to 20GA 3" Chamber - Shotgun Adapter

Precision machined from  stainless steel

Proudly made in the USA

This adapter will only fit a barrel with a three inch chamber, it will not fit a 2 3/4 inch chamber. We do have a 12GA to 20GA adapter for 2 3/4 inch chambers, please see our other products.

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 3 inch 12GA shell.  It will easily fit into your break open shotgun barrel and accept any 20GA 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 cartridge side is precision CNC machined to the exact chamber dimensions to accept 20GA shotgun ammunition (SAAMI chamber specifications).  This adapter is machined to fire any length 20GA ammunition up to three inches, this is a perfect turkey shot adapter.

Every adapter is laser engraved for easy caliber conversion identification.

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