Description
12GA to 357 Magnum Shotgun Adapter Chamber Reducer

12GA to 357 Magnum & 38 Special - 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 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 12GA 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).

Adapter orientation is not important and the adapter will  work in any position. 
Made in the USA on American machines by American workers  ......... support USA made products and companies!
Will fit any break open shotgun with 2 3/4" or 3" chambers
Perfect for 'Preppers' or your Bug Out Bags.  Carry one gun and have the ability to shoot not only 12GA shells but also 357 Magnum and 38 Special ammunition.

Surprisingly accurate!
Not recommended for pump action or semi-auto shotguns.  Designed for use with break open style shotguns.


Any ammunition pictured is for representation purposes only and is not included with this purchase.

We've test fired these adapters and at 50 feet with an old junky shotgun (with no sights) we were able to achieve groups of 3"-5" easily.
