This is a thirty round magazine for use on M1 Carbine rifles, type IV configuration, blued steel body, baseplate, and follower. The bolt remains open when the last round is fired. When using this magazine on an Iver-Johnson or a Universal model you need to file a little stud off.
Specific state laws prohibit the sale and shipment of this magazine; we CANNOT sell or ship to California, Maryland, Hawaii, Massachusetts, New York, and New Jersey.
Use MAG-345 instead.
