12GA to 444 Marlin - SMOOTH Bore Shotgun Adapter

Designed for break-open style shotguns 

Precision machined from stainless steel

Proudly made in the USA

This is a 3 inch long Smooth Bore Adapter

This adapter gives your 12 Gauge single or double shot  break open shotgun the ability to fire 444 Marlin ammunition.  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 444 Marlin ammunition.  After firing simply remove the adapter and tip upside down to remove the spent 444 Marlin shell.  This adapter has a SMOOTH bore, this in NOT a rifled bore adapter, again this adapter has a smooth bore.  The 444 Marlin chamber side is precision CNC machined to the exact chamber dimensions to accept 444 Marlin ammunition (SAAMI chamber specifications).

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