[QUOTE="NesikaChad, post: 268243, member: 7449"] The problem with trying to hardness test a finished action is that it is a rather challenging task to fixture the thing. If you lay it in a "V" block and "ding it" you will get a false reading every time. It's going to read harder than what it really is. The reason is the receiver is going to flex and this will absorb some of the pressure exerted during the test. The diamond won't penetrate as far and it'll indicate being harder than what it really is. The best answer to mitigate this is to saw a ring off, grind it flat, and then test it on edge. Of course this is a bad idea when it's your action since its destroyed in the process. This was a problem we faced at Nesika and the only way to really mitigate it is to alter the manufacturing order of operations a bit. It's a little more of a challenge to machine this way since the hardness goes up, but with SS it kinda works to your advantage because the material leaves a better finish as long as you use sharp tools and are a little conservative with speeds/feeds. The only possible way I can think of that might work is to machine a slug from the same material as the receiver and thread it into the action. What your trying to do is fool the action into thinking its a solid piece of material again. I don't know if it'll work or not and the only way to really know is to again ruin the receiver by cutting the ring, grinding, and testing. When in doubt, send the thing back to the manufacturer. I'd advise you tell the GS to just stop and send it back. [/QUOTE]
