12GA to 17HMR - SMOOTH Bore Shotgun Adapter
Designed for break-open style shotguns
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 17HMR ammunition (Hornaday Magnum Rifle). This adapter is precision machined from high quality stainless steel to the OD specifications of a 2 3/4 12GA shotgun shell. It will easily fit into your break open shotgun barrel and accept any 17HMR ammunition. After firing simply remove the adapter and tip upside down to remove the spent 17 HMR shell or use your finger nail to grab and remove the shell while the adapter stays in your gun. The wide groove cut in the face will not only allow you to easily remove a spent shell but also provides a recessed clearance area for your firing pin. Adapters that don't have this recessed area (or recessed area in the wrong spot) do not provide the proper clearance for your firing pin and may damage your shotgun. A SMOOTH bore is reamed through the adapter for the bullet.
This adapter has a SMOOTH bore, this in NOT a rifled bore adapter, again this adapter has a smooth bore. The 17 HMR cartridge side is precision CNC machined to the exact chamber dimensions to accept 17HMR ammunition (SAAMI chamber specifications).
Adapter orientation is not important and the adapter will work in any position.

Surprisingly accurate!
DO NOT use in pump action or semi-auto shotguns. Designed for use with break-open style shotguns only. The risk is that the bullet could fall out of the adapter causing a dangerous result. Also, it could damage the adapter upon ejection. Do not dry fire your shotgun with this adapter. Dry firing is firing your shotgun with the adapter in the chamber and without a 17HMR cartridge in the adapter.
Any ammunition pictured is for representation purposes only and is not included with this purchase.
We've test fired these rifled adapters and they are surprisingly accurate!
