Bottom metal for Mauser 98 standard action with a screw spacing of 7.835" . This got a double set trigger unit installed, common for European made custom sporter rifles. The traditional European solution to get the trigger pull down to a hair trigger. The rear trigger compresses a spring that is getting released by pulling the front trigger that has only a few ounces pull weight. Has a set screw to fine tune that weight. This gets fitted into the bottom metal and the kick off replaces the military trigger in the sear. Requires installation by a qualified gunsmith.
