12GA to 10MM - 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 a 10MM bullet.  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 10 mm ammunition.  After firing simply remove the  adapter and tip upside down to remove the spent 10mm shell.  A smooth bore is gently bored through the adapter for the bullet  (no rifling).  The 10mm bullet side is precision CNC machined to the exact chamber dimensions to accept 10mm ammunition (SAAMI chamber specifications).

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