I wish I could answer that with 100% confidence. However, best guess is Tennon 1.503 / Face to Receiver 1.635 so 0.132 +/- with case protrusion .128 +/-. Your question likely just cost me a proper depth mic. Either way, still just curious how many others are seeing this?What’s the gap between your bolt head and the back of your barrel?
