I have a masterpiece arms 65 BA comp switch lug with the axiom action and TT diamond. The issue is the barrel would not loosen from the action despite the switch lug being loosened. The barrel would easily unscrew once 1/2 turn of the front action screw was released. The action was tightened with everything in place and the chassis measured .010” of flex, not much at all for the barrel to bind.
Phil from MPA had not heard of this issue and went above and beyond to assist me. He played with his personal rifle to find the problem. It was discovered the recoil lug was sitting on top of the recoil lug tension device. The screw directly in front of the front action screw must be loose and pressed upwards as the action screws are tightened to ensure it functions a intended. Once the action screws are hand tight the recoil lug tension screw can be tightened then everything snugged to spec.
You can see in the picture where the recoil lug was digging into the tension device. I hope this helps someone out who might have this issue as well.
