The design is available for purchase.

The Mauser 45 Winchester Magazine Adapter is designed to use the M1 carbine magazines. These are adapters that we made years ago and are offering them again due to request. Each kit comes with a military profile barrels in either large ring or small ring. This conversion will work in most Mauser including the M48 action. The 45 Winchester Magnum is a superb round for hunting but may not be legal in all states. This conversion is a bit more involved and the online instructions can be downloaded for viewing to see if this is for you. It requires lining up the front and rear mag adapter and drilling/cross pinning. The M1 magazine also requires a bit of modification to work with the 45win mag cartridge. This kit includes the adapter blocks, mounting pins and extended ejector.
