You'll need to fix more than the trigger to get the most out of it. The AT bug is a result of sear geometry and requires replacement, as well the trigger needs to be modified, and new sear and trigger spring installed. The bolt sled requires replacing and the back of the body cnc machined to suit with more clearance. Also the front guide needs a counterbore to suit an improved puller guide with a step added to prevent action over travel, instead of relying on the sled/backblock. Also the valve stem and seal should be swapped for a palmers one. Fun times with obsolete prototypes
