12GA to 40 S&W Shotgun Adapter - Chamber Reducer - Stainless Steel

12GA to 40 S&W - 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 40 S&W 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 40 S&W ammunition.  After firing simply remove the adapter and tip upside down to remove the spent 40 S&W 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 40 S&W 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 40 S&W ammo.
Surprisingly accurate!

NOT recommended for pump action or semi-auto shotguns.  Designed only for use with break open style shotguns. Usage in a pump action creates a risk of the bullet falling out causing a dangerous result.
It may also chew up the side of the adapter upon ejection.

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.
