This adapter gives your 12 Gauge single or double shot  break open shotgun the ability to fire a 40S&W bullet (standard 40 Smith and Wesson caliber).  This adapter is precision machined from high quality stainless steel to the OD specifications of a 2 3/4 12GA shell plus and extra half inch in front to make this adapter three inches long in total.  It will easily fit into your break open shotgun barrel  and accept any 40S&W ammunition.  After firing simply remove the adapter and tip upside down to remove the spent 40S&W shell.  This adapter has a rifled bore to increase accuracy, this in NOT a smooth bore adapter, again this adapter has a rifled bore.  The 40S&W cartridge side is precision CNC machined to the exact chamber dimensions to accept 40S&W ammunition (SAAMI chamber specifications).

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