20GA to 357 Magnum & 38 Special - Shotgun Adapter

Precision machined from stainless steel

Proudly made in the USA

This adapter gives your 20 Gauge single or double shot  break open shotgun the ability to fire 357 Magnum and 38 Special ammunition.  This adapter  is  precision machined from high quality stainless steel to the OD  specifications of  a 2 3/4 20GA shell.  It will easily fit into your  break open shotgun barrel and accept any 357 Magnum and 38 Special 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 for the bullet  (no rifling).  The bullet side is precision CNC machined to the exact  chamber dimensions to accept 357 Magnum and 38 Special ammunition (SAAMI chamber specifications).  This adapter has a smooth bore and is NOT rifled.  We do offer a 357Mag rifled adapter, please check our other listings.

Every adapter is laser engraved for easy caliber conversion identification.
