Mauser 300 AAC Blackout for small ring

These are barrels chambered for the 300 AAC blackout and made for Mauser small ring actions. You will need to modify the extractor and bolt face for this one to work. However once converted it will transform your Mauser to a rifle that is safer to use in the old actions. These are 18″ long and feature a 5/8″-24 muzzle threads and include the barrel lock ring that we use on all Mauser actions and is similar to Savage barrel lock rings.
