One thing that people might easily miss is the large spreadsheet that details the specs of all BAT Machine actions. To download that .xlsx spreadsheet to your hard drive, Right Click (and “Save As”) this link: ACTION CONFIGURATION PART LIST. After opening the spreadsheet, on the “ACTION” worksheet, you’ll find action model, body shape, weight, bolt faces available, and tenon spec among several other items. Note that there are two worksheet tabs (look down at the bottom left). Use these spreadsheet tabs to switch between “Action” and “Accessories”.

Also, on the BAT website FAQ page, you’ll find prints for barrel tenon machining, firing pin sizes, torque specs, and tons of other very helpful info. This is well worth a look. — ELR Researcher.
