20GA to 380 ACP - 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 380ACP 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 380 ACP ammunition.  After firing simply remove the  adapter and tip upside down to remove the spent 380 ACP shell.  A smooth bore is gently  bored through the adapter for the bullet  (no rifling).  The 380 ACP bullet side is precision CNC machined to the exact chamber dimensions to accept 380 ACP ammunition (SAAMI chamber specifications).

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